What is Polygram ?

→ A Polygram is a regular n-sided polygon with identical isosceles triangles (also known as SPIKES) attached to each edge. → It looks like a n-pointed star. → For a n-pointed star, there will be n-spikes. → The Spike (Isosceles Triangle) is an important part of the polygram and it is defined using 4 parameters. They are : 1) The Base Length of the Triangle (a.k.a Base Length of the Polygram) 2) Length of the equal side of the triangle (a.k.a Edge Length of the Polygram) 3) Angle between the two equal sides of the isosceles triangle (a.k.a Inner Angle angle of the Polygram) 4) Height of the triangle (a.k.a Spike Height) Apart from these there are other important parameters that define the Polygram. They are: 1) Outer Angle : The angle between two adjacent isosceles triangles. 2) Chord Length : The distance between two peaks of the adjacent Spikes of the Polygram. 3) Perimeter : The sum of lengths of all the edges of the polygram. 4) Area : The amount of space occupied by the polygram.
