Question

verify the formula for number of diagonals of a triangle​

Answer 1

Answer:

Now the number of diagonals of any n sided polygon can be found out using the direct formula d=n(n−3)2 where d is the number of diagonals and n is the number of sides of the polygon. (n-3) multiply by the number of vertices and divide by 2. So the number of diagonals in a triangle are 0. Hence option (A) is correct.
