Simple Formulas related to Polygons and Angle Conversion

Conversion of Angles

Converting Angle in Degree From Radian

Angle A radian to Degree:

A rad = A*(180/pie) degree

Converting Angle in Radian From Degree

Angle A degree to radian:

A degree = A*(pie/180) rad

Note: where pie=22/7 (or 3.14); rad is used for radian.

Angles of Regular Polygon

))> Angles in a regular polygon:-

 n = 360 / (180-A)     =>     A = 180 (n-2) / n

))> An angle of polygon with n Angles:-

A = 180 (n-2)

Note:  where A is an angle of a regular Polygon.
