A regular polygon.
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
This is a tautological question that does not have a proper answer. A regular polygon is one which has all its sides of equal length and all its interior angles of equal measure.
it's a regular polygon
Equiangular
If all of the interior angles of the polygon add up to 180 degrees, then the polygon is a triangle.
yes always
If the polygon is a regular polygon then all interior angels are equal to 180-(360/no of sides of the polygon)
Only if the polygon is a "regular" one.
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.
It is a regular polygon providing that its interior angles are equal as well.
