what are the properties of cyclic quadrilateral |
| Answer» A cyclic quadrilateral is a quadrilateral that can be inscribed in a circle, meaning that there exists a circle that passes through all four vertices of the quadrilateral.\tIf one side of the cyclic quadrilateral is produced, then the exterior angle so formed is equal to the interior opposite angle.\tThe sum of the opposite angles of a cyclic quadrilateral is supplementary.\tIn a cyclic quadrilateral, the ratio of the diagonals equals the ratio of the sum of products of the sides that share the diagonal\'s end points.\tPerpendicular Bisectors of a quadrilateral are concurrent only if it is a cyclic quadrialateral. | |
