How do you find the diagonal of a shape?

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).

How do you solve a diagonal question?

What is the side of a square whose diagonal is 16 cm?

Substituting a=16 in the above expression, the length of diagonal of the square whose side is of length 16cm is =16√2cm. Hence, the length of diagonal of the square whose side is of length 16cm is 16√2cm.
