## Outer angle of Polygram Solution

STEP 0: Pre-Calculation Summary
Formula Used
Outer angle = (2*pi/Number of Points)+Inner angle
AngleOuter = (2*pi/Npoints)+AngleInner
This formula uses 1 Constants, 2 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
Number of Points- Number of Points gives the number of corner points in the geometrical shape.
Inner angle - Inner angle is the interior angle of any geometric figure. (Measured in Degree)
STEP 1: Convert Input(s) to Base Unit
Number of Points: 5 --> No Conversion Required
Inner angle: 270 Degree --> 4.7123889803838 Radian (Check conversion here)
STEP 2: Evaluate Formula

## 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 an n-pointed star. For an 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.
