A regular polygon is a closed figure made of line segments.
True or False: A regular polygon is a closed figure made of line segments.

A regular polygon is a closed figure made of line segments.
True or False: A regular polygon is a closed figure made of line segments. False, it has sides of equal length and angles of equal measure. Example:

True or False: Give an answer for each statement.
