Cyclic quadrilateral circumradius ( Parameshvara's formula )
Description
In Euclidean geometry, a cyclic quadrilateral or inscribed quadrilateral is a quadrilateral whose vertices all lie on a single circle. This circle is called the circumcircle or circumscribed circle, and the vertices are said to be concyclic. The circumradius of a Cyclic quadrilateral is related to its successive sides and the semiperimeter of the Cyclic quadrilateral.
