Question

plz tell me fomula to find diagonals of polygon​

Answer 1

Answer:

The number of diagonals in a polygon that can be drawn from any vertex in a polygon is three less than the number of sides. To find the total number of diagonals in a polygon, multiply the number of diagonals per vertex (n - 3) by the number of vertices, n, and divide by 2 (otherwise each diagonal is counted twice).

Answer 2

Answer:

exterior angle of a polygon = 360 ÷ number of sides.

interior angle of a polygon = sum of interior angles ÷ number of sides.
