Yup.. I got it, in shortest way u can say that(n-2)180 is the formula to calculate sum of interior angles rightStep1- Divide the polygon into triangles using full diagonalsStep 2- Interior angles of a triangle add up to 180° (anglesum prop. of triangle).... Is it correct??

We know that if a polygon has ‘n’ sides, then it is divided into (n – 2) triangles.We also know that, the sum of the angles of a triangle = 180�.Therefore, the sum of the angles of (n – 2) triangles = 180 � (n – 2) = 2 right angles � (n – 2) = 2(n – 2) right angles = (2n – 4) right anglesTherefore, the sum of interior angles of a polygon having n sides is (2n – 4) right angles.Thus, each interior angle of the polygon = (2n – 4)/n right angles.
