WebFeb 1, 1977 · The expression for the circumradius of a cyclic quadrilateral in terms of … A cyclic quadrilateral with successive sides a, b, c, d and semiperimeter s has the circumradius (the radius of the circumcircle) given by This was derived by the Indian mathematician Vatasseri Parameshvara in the 15th century. Using Brahmagupta's formula, Parameshvara's formula can be restated as where K is the area of the cyclic quadrilateral.

WebCyclic Quadrilaterals. Cyclic quadrilaterals (In Euclidean geometry) are closed quadrilateral whose all vertices lie on a single circle. This circle is called the circumscribed circle or circumcircle, and the vertices are said to be concyclic . The center of the circle is called the circumcenter and its radius is known as the circumradius . WebEnter the email address you signed up with and we'll email you a reset link. purdue northwest oit
