If all of its interior angles are equal then it is a regular polygon
Only when it is a regular polygon that all interior angles are of equal measure
it's a regular polygon
A regular polygon has all equal sides and all equal interior angles
If all of the interior angles of the polygon add up to 180 degrees, then the polygon is a triangle.
Only if the polygon is a "regular" one.
If the polygon is a regular polygon then all interior angels are equal to 180-(360/no of sides of the polygon)
A regular polygon has all equal interior angles and all equal sides of the same length
An irregular polygon has not got all equal sides and all equal interior angles.
A polygon with all interior angles congruent Is known as a regular polygon.
