∴ ∠opq = ∠oqp (angles opposite to equal sides are equal). When a quadrilateral is inscribed in a circle, you can find the angle measurements of the quadrilateral in just a few quick steps! Inscribed quadrilaterals are also called cyclic quadrilaterals. This circle is called the circumcircle or circumscribed circle, and the vertices are said to be concyclic. Interior angles that add to 360 degrees In geometry, an inscribed angle is the angle formed in the interior of a circle when two secant lines intersect on the circle. If a quadrilateral inscribed in a circle, then its opposite angles are supplementary. Lesson on inscribed quadrilaterals and examples worked out. Follow along with this tutorial to learn what to do!
