Question

Is is true that a regular polygon has all sides of the same length and all internal angles the same?

Answer 1

True

Explanation:

A regular polygon has all sides of the same length and all internal angles the same.

Both conditions are necessary.

For example, a rectangle has all angles the same, but is not generally regular and a rhombus has all sides of the same length, but is not generally regular.

A square is a regular four sided polygon, i.e. a regular quadrilateral.
