A polygon has 90 diagonals

Last updated on Feb 13, Get Started. English Hindi.

In Geometry, diagonals of a polygon are line segments joining two non-adjacent vertices. A square given below has two pairs of non-adjacent vertices. By joining the vertices of these two pairs, we get two diagonals of a square. Hence, AC and BD are diagonals of a square. The formula to find the diagonal of a polygon square is:. We can use this formula to find the diagonals of a polygon with any number of sides.
