How to Draw a Star on a Coordinate Plane

Drawing a star may seem simple and overwhelming at the same time. For instance, how to construct a five- or a seven-pointed star and make your drawing technically correct? If this theme is something you're interested in, let'southward swoop into the fascinating world of stars and geometry.

In this tutorial, I'll testify you the fashion to design different kinds of stars, from a three-pointed to an eight-pointed one. We'll use ordinary tools like a ruler, a graphite pencil, compasses, and a protractor.

As a fun bonus, nosotros'll also explore a style to draw a five-pointed star in a casual manner, without any serious measurements.

I recommend post-obit this tutorial from kickoff to finish; every part demonstrates the common basic features, just an understanding of the simpler examples will help you to master more than circuitous methods.

If yous're interested in this type of tutorial, we have a whole series of Geometric Drawing tutorials which y'all may also enjoy.

What You Will Need

Y'all will need the following equipment to complete this project:

• a graphite pencil (I recommend using an HB or H type, and delight make sure information technology's abrupt)
• a pair of compasses
• a protractor
• a ruler
• an eraser
• an ink pen (an optional tool)
• drawing paper

ane.How to Draw a Three-Pointed Star

Pace ane

I mark the cardinal signal with a graphite pencil, and so describe a small circumvolve of an capricious radius, using the compass. It's of import to leave enough space effectually this circle.

Proceed your pencil marks light, but in instance you determine to erase the subsidiary lines later on.

Pace 2

I depict a bigger circle, using the central betoken as a reference.

Step iii

I draw a straight line that is going upwards from the centre of the circumference. If you lot need perfectly fifty-fifty lines, brand sure yous use a ruler.

Step 4

A circle has 360 degrees. To depict a three-pointed star, we should create three equal sectors; 360 divided by 3 is 120.

With a protractor, I construct a sector that has an angle of 120°. The central point and the vertical line are our references for the measurements.

Pace five

I create another sector of the circle with the bending of 120°. At present we have three lines; the points where they see the bigger circumference are the apexes of our star.

Step 6

It's time to divide each sector in two. With the protractor, I find the angles of 60° and mark the segments with dashed lines.

I also marking the points of intersection where these lines cross the small-scale circle.

Footstep vii

I connect the points with the apexes. Now nosotros have a beautiful three-pointed star!

Step viii

I outline the contours of the star, using an ink pen.

This step isn't obligatory; it's but useful to emphasize the main lines of the figure. You lot can erase all subsidiary pencil lines or leave them—it's completely upwardly to you.

2. How to Draw a Four-Pointed Star

Step ane

I draw a small circle of an arbitrary radius, using a pencil and a compass.

Footstep ii

I add a bigger circle that is encircling the existing 1.

Step 3

I add together a straight vertical line going from the center of the circle.

Step 4

With the protractor, I find a xc° angle and create the first sector.

I add together two more than lines, based on the aforementioned method; now we have four sectors, each with an angle of 90°. The points where the lines cross the bigger circumference are the apexes of our star.

Step 5

Let's split up each sector in one-half. To do that, I discover the angle of 45° inside each sector and mark the new segments with dashed lines.

I as well mark the points of intersection, where these lines cross the pocket-sized circle.

Pace six

I connect the points with the apexes, using straight lines. The four-pointed star is complete!

Step 7

I outline the contours of the star, using the ink pen.

3. How to Draw a Five-Pointed Star

Step ane

I mark the cardinal betoken with a pencil, and then draw a relatively big circle of an arbitrary radius, using the compass.

Step two

I add together a vertical line that is going from the key signal of the circumvolve.

Step 3

Let'due south find the first sector with a protractor; its angle should be 72°.

Using the same principle, I add more than lines. Now nosotros have five sectors; the points where the lines cross the circumference will be the apexes of our star.

I also name these points with letters, only to simplify the process and make it visually clear.

Step 4

I connect the points A and B with a direct line.

Step 5

I connect the points A and C with a line.

Step 6

In the same manner, I bring together the indicate B and the betoken D.

Step 7

I connect the point E with the points D and C. The shape is complete!

Step eight

With an ink pen, I outline the contours of the star, and so erase the unnecessary captions.

four. How to Depict a Six-Pointed Star

Stride 1

I mark the central point and draw a relatively big circle of an capricious radius, using the compass.

Step 2

I add a directly vertical line from the center of the circumvolve.

Stride three

To describe a six-pointed star, we need to create six equal sectors, each with an angle of 60°.

I create the showtime sector, using the protractor.

I add together the sectors, using the aforementioned principle, and proper noun the points of intersection with messages.

Footstep 4

I connect the points A and B.

Step 5

At present I connect the points B and C.

Stride 6

I connect another pair of points, this time A and C. Now we have a triangle.

Stride 7

I connect the points D and E with a straight line.

Step 8

I join the points E and F.

Step 9

I connect the points D and F; at present we have some other triangle, and the shape of the hexagram is consummate.

Stride 10

I outline the contours of the star with black ink pen lines.

Pace 11

Past the way, there is some other method of drawing a six-pointed star, this time without a protractor. Permit's try this option!

I draw a circumference of an arbitrary radius, using the compass.

Step 12

I add together the lines (a vertical and a horizontal ane) that are going correct through the key point of the circle. Let'south hold that the upper indicate of intersection is the point A.

Step 13

Put the needle indicate of your compass right into the indicate A, and measure the distance between this point and the center of the circle.

Then, without removing the needle point, measure the same distance on the circumference. You lot'll get the point C on the right side and the point B on the left side.

Repeat this activeness several times, shifting the needle point of the compass, and name the points you become with messages.

Step 14

I connect the points A and D, A and E, and D and E with straight lines. Now we have the first triangle.

Step fifteen

I connect the points B and C, C and F, and F and B with direct lines. We get the second triangle, and the star is consummate!

5. How to Draw a 7-Pointed Star

Step 1

I draw a circumference of an arbitrary radius, using the compass.

Footstep ii

I draw a straight vertical line that is going downwards from the cardinal point of the circle.

Step iii

When 360 is divided by seven, we get a fractional number, so we have to choice the closest value (51°). I create a set up of sectors that have angles of 51°, using the vertical line equally a reference.

I also proper name the points of intersection with letters.

Stride 4

I connect the indicate A with the points B and C.

Step 5

I join the points B and D.

Step 6

I connect the points D and East.

Step vii

I join the points E and F.

Step 8

I connect the points F and G.

Footstep 9

I connect the points G and C. The shape is consummate!

Step x

I outline the contours of the heptagram, using the ink pen.

half dozen. How to Depict an Eight-Pointed Star

Step 1

I draw a circumference of an arbitrary radius, using the compass.

Footstep 2

I add together a direct vertical line that is going upwards from the center of the circle.

Pace 3

360 divided by viii is 45, so we take to construct the sectors that take angles of 45° each. I create the first sector, using the existing vertical line as a reference.

I complete the fix of sectors and proper name the points of intersection.

Step four

I connect the points A and D with a directly line.

Step 5

I connect the points D and G.

Step 6

I join the points G and B.

Step vii

I connect the points B and E.

Footstep 8

I connect the points E and H. Do you foresee where the adjacent line will be?

Pace nine

I bring together the points H and C.

Step 10

I connect the points C and F.

Step 11

I connect the points F and A. The octagram is complete!

Step 12

I outline the contours of the star with ink lines.

7. How to Draw a Five-Pointed Star in a Casual Fashion

Footstep 1

Are you tired of making calculations and measuring everything? The serious office is over, so allow'south relax and draw a pentagram in a casual manner.

I describe a straight inclined line, using a pencil and a ruler. You tin can use a ruler, likewise, or draw the lines just by hand.

Step ii

I draw some other inclined line, starting from the top indicate of the existing one. Now we have a profile resembling an upturned "v" letter.

Pace 3

I add another line going to the left-hand side.

Footstep 4

I add together a directly horizontal line.

Footstep 5

I complete the shape of the star, connecting the points with a finishing line.

By the way, it'southward possible to draw a star post-obit the same method, past marker all 5 points beforehand and and then connecting them with lines.

Your Drawings Are Complete

Congratulations—you did it! Now you can depict dissimilar kinds of stars. I hope the compass and protractor became your best friends, and together y'all'll create many more geometrical objects.

Creating technically perfect figures requires skill and patience, and so if your stars came out slightly uneven at the kickoff try, don't give upwards—just endeavour again. Sometimes the tools we use let imperfections, similar the inaccuracy of the protractor'due south grid.

At the aforementioned fourth dimension, remember to have fun and enjoy the process!
