Answer 2

The ratio between the diagonals and the sides can be defined and is known as Cyclic quadrilateral theorem. If there's a quadrilateral which is inscribed in a circle, then the product of the diagonals is equal to the sum of the product of its two pairs of opposite sides.The ratio between the diagonals and the sides can be defined and is known as Cyclic quadrilateral theorem.
