Question

Number of diagonals of n sided polygon​

Answer 1

Answer: N[N-3]/2

Step-by-step explanation

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).

Answer 2

Number of diagonals of n sided polygon =

$\frac{n ( n - 3 )}{2}$
