Properties of regular pentagons:
Interior angle :108° Like any regular polygon, to find the interior angle we use the formula (180n–360)/n . For a pentagon, n=5.
Exterior Angle 72°
To find the exterior angle of a regular pentagon, we use the fact that the exterior angle forms a linear pair with the interior angle, so in general it is given by the formula 180-interior angle.

A regular pentagon is a five sided figure that has 108degrees on each side. The formulae to finding out the total angle is
y = 180x -360
where x is the number of sides
and y is the total degrees
