A compass because a protractor is for measuring angles
To draw a decagon using a compass, start by drawing a circle with the compass. Mark the center of the circle and label it as point O. Then, divide the circle into ten equal arcs by first finding the radius and using a protractor to measure 36-degree angles (360°/10). Finally, use the compass to mark each point around the circle, and connect these points to form the decagon.
You use a protractor
You use a protractor to meausure angles in degrees. Or you can draw a semi-circle (my favorite) ;)
You can draw a circle in assembly program by using a compass-like tool. Secure the tip of the compass and then rotate the compass tool so that it completes the circle.
To inscribe a regular polygon in a circle, first, determine the number of sides (n) for the polygon. Draw a circle with a compass to represent the circumcircle. Using a protractor or a compass, divide the circle’s 360 degrees by n to find the angle between each vertex. Mark these points on the circumference, and then connect them with straight lines to form the regular polygon.
If you have a protractor: Draw a line from the center of the circle to the outside (radius), then measure 60 degrees and draw another line. If you have a compass: Draw a circle using the compass, then, using your compass, place the compass needle on the edge of the circle, draw another circle (KEEP THE RADIUS THE SAME). Your two circles should have two intersection points. Place the needle on one of the intersection points and repeat the process. I suggest you look at:

Construct a circle with a compass and then draw a straight line through its centre
a circle is 360 degrees. 1 5th = 360/5 = 72 degrees mark a starting point and draw a straight line and using a protractor find 72 degrees from that point and draw a line to that. now using a string or compass trace the arc between the 2 lines. You now have a wedge that is 1 5th of the circle.
