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.An example of a quadrilateral that cannot be cyclic is a non-square rhombus.A cyclic quadrilateral is a quadrilateral drawn inside a circle. Every corner of the quadrilateral must touch the circumference of the circle. The second shape is not a cyclic quadrilateral.The opposite angles in a cyclic quadrilateral add up to 180°.
