What are the properties of a regular polygon?

Answer 1

All the sides of a regular polygon must be the same length and each angle of must be of the same measure.

Answer 2

A regular polygon has several properties:

1. All sides are equal in length.
2. All angles are equal in measure.
3. The sum of the interior angles is (n-2)180 degrees, where n is the number of sides.
4. The sum of the exterior angles is 360 degrees.
5. The diagonals, which are line segments connecting non-adjacent vertices, are congruent in length.
6. The polygon has rotational symmetry, which means it can be rotated by a certain angle around its center to coincide with its original position.
