Question

Find the number of diagonals in an octagon

Answer 1

Hi there,
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).

Therefore,

There are 20 diagonals in a regular octagon.
