WebConstructible polygon. In mathematics, a constructible polygon is a regular polygon that can be constructed with compass and straightedge. For example, a regular pentagon is constructible with compass and straightedge while a regular heptagon is not. There are infinitely many constructible polygons, but only 31 with an odd number of sides are ... WebNote: If you are not given the center, you can find it using the method shown in Finding the center of a circle with compass and straightedge. 1. Draw a diameter of the circle through the center point and mark its endpoints C …
