what are the angles of an equilateral pentagon
Equilateral pentagon In geometry an equilateral pentagon is a polygon with five sides of equal length. Its five internal angles, in turn, can take a range of sets of values, thus permitting it to form a family of pentagons. The requirement is that all angles must add up to 540 degrees and must be between 0 and 360 degrees but not equal to 180 degrees. In contrast, the regular pentagon is unique, because it is equilateral and moreover it is equiangular (its five angles are equal; the measure is 108 degrees).
Perpendicular The legs of a right triangle are perpendicular to each other.
Dodecagon In geometry, a dodecagon or 12-gon is any twelve-sided polygon.
Heptagon In geometry, a heptagon is a seven-sided polygon or 7-gon.
