Which regular polygons can be constructed from the construction?
Which regular polygons can be constructed from the construction?
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.

Where do the words polygon and gon come from?
They are made of straight lines, and the shape is “closed” (all the lines connect up). Polygon comes from Greek. Poly- means “many” and -gon means “angle”. A regular polygon has all angles equal and all sides equal, otherwise it is irregular
