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.
An irregular polygon has not got all equal sides and all equal interior angles.
A regular polygon has all equal interior angles and all equal sides of the same length
It is a regular polygon providing that its interior angles are equal as well.
