Specification G1, G3 · Paper 1, Paper 2, Paper 3
A polygon whose sides are all equal in length and whose interior angles are all equal.
Specification G1, G3 · Paper 1, Paper 2, Paper 3
A polygon with all sides equal in length and all interior angles equal.
Revise: Geometric Terms and NotationsA regular polygon has both equal sides and equal interior angles. A square is regular, but a non-square rectangle is not: its angles are equal while its side lengths are not all equal. Polygons that do not meet both conditions are irregular.
A polygon with all sides equal in length and all interior angles equal in size.

A polygon with all sides equal in length and all interior angles equal in size.
Revise: Polygon ClassificationA regular polygon has both equal-length sides and equal-sized interior angles. An equilateral triangle and a square are regular polygons. If either the sides or the angles differ, the polygon is irregular.
A polygon whose sides are all equal and whose interior angles are all equal.
Check whether the question asks for the sum of all interior angles or the size of one angle of a regular polygon.
For a regular polygon, find one exterior angle using ; an interior angle is minus that exterior angle.
Check whether the question asks for the sum of the interior angles or one interior angle of a regular polygon. Divide by only when finding one equal angle.
