How does the Polygons Calculator work?

Free Polygons Calculator - Using various input scenarios of a polygon such as side length, number of sides, apothem, and radius, this calculator determines Perimeter or a polygon and Area of the polygon.
This also determines interior angles of a polygon and diagonals of a polygon as well as the total number of 1 vertex diagonals. This calculator has 5 inputs.

What 13 formulas are used for the Polygons Calculator?

P = n x s A = s^{2}n/4tan(π/n) Interior Angle Sum = (n - 2) x 180° Diagonals = n(n - 3)/2 1 vertex Diagonals = n - 3 Triangles = N - 2 5 sides = Pentagon 6 sides = Hexagon 7 sides = Heptagon 8 sides = Octagon 9 sides = Nonagon 10 sides = Decagon
