Formula for no of sides of polygon
WebApr 9, 2024 · The answer is to multiply the number of sides of a polygon. Step 1 - The sum of all the inner angle degrees is (n - 2) 180. Subtract 2 from the number of sides of a … WebSince there are n sides, the remaining n (n − 1) / 2 − n n(n-1)/2 -n n (n − 1) /2 − n of them are the diagonals of a convex polygon. Another way to express the general rule for the total number of diagonals is to think about the number of diagonals that can be drawn from each vertex in a polygon. That is "3" less than the number of sides.
