A regular shape, also known as a regular polygon, is a shape that has sides that are all equal. If there are sides of differing lengths, these shapes are known as irregular polygons.
Know MoreAs well as having all sides equal in length, all interior angles must also be the same. For example, a triangle with three sides of equal length and all three internal angles of 60 degrees, which is also known as an equilateral triangle. However, not all regular shapes are equilateral because while an equilateral polygon can have all sides exactly the same length, they must also have the same internal angles.

Full Answer >A regular pentagon has rotational symmetry. The order of its rotational symmetry is five, because it can be rotated into five different configurations that look exactly the same before returning to its original configuration. The angle of rotation for each turn is 72 degrees.
Full Answer >The internal angles of a regular decagon are 144 degrees each. A decagon is a polygon with 10 sides and 10 internal angles, and a regular decagon is a polygon with 10 equal sides and 10 equal angles.
Full Answer >A regular quadrilateral is also called a square. Regular polygons are two-dimensional shapes in which all sides are of equal length and all angles are of equal breadth. A quadrilateral is any four-sided polygon. A square has four sides and four angles, all of equal size.
