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). </P> <P> Four intersecting equal circles arranged in a closed chain are sufficient to determine a convex equilateral pentagon . Each circle's center is one of four vertices of the pentagon . The remaining vertex is determined by one of the intersection points of the first and the last circle of the chain . </P>
