If you know how to use a protractor and a compass, you can draw a perfect star!
Use a compass to draw a circle the size you want your star to be.
Draw a second, smaller circle inside the first, using the same center point. Make the second circle about half the size of the first.
Draw a line from the edge of the outer circle to the center point using a ruler.
Place a protractor on the line, with the center hole of the protractor over the center point of the circle.
Measure and mark every 72 degrees around the circle (72, 144, 216, 288 and 360 degrees), dividing the circle into five even sections.
Line the ruler up with the center point of the circle and one of the marks you just made.
Draw a line from the edge of the outer circle, through the center point, ending at the edge of the inner circle.
Continue drawing lines as described until you have drawn the five lines, which evenly divide the circle.
Connect the top of one of the lines that touches the outer circle to the lines that touch the inner circle on both sides, forming a point.
Continue to connect the lines around the circle until you have made a five-point star.
Make the inner circle larger for a fatter star or smaller for a thinner star. Draw your star on poster board and cut it out to use as a pattern for drawing more. To make a six-point star, measure and mark every 60 degrees (60, 120, 180, 240, 300, and 360 degrees), dividing the circle into six even sections. To make an eight-point star, measure and mark every 45 degrees (45, 90, 135, 180, 225, 270, 315, and 360 degrees), dividing the circle into eight even sections.
Handle a compass carefully; it has a very sharp point.
