Question

the number of Dioganal in a polygen of n side is​

Answer 1

the number of dioganal in polygen = n-3/2

Answer 2

Answer:

The number of diagonals in a polygon = n(n-3)/2, where n is the number of polygon sides. For a convex n-sided polygon, there are n vertices, and from each vertex you can draw n-3 diagonals, so the total number of diagonals that can be drawn is n(n-3).
