Angles In Inscribed Quadrilaterals - Cyclic quadrilaterals.pptx : An inscribed angle is the angle formed by two chords having a common endpoint.. In euclidean geometry, a cyclic quadrilateral or inscribed quadrilateral is a quadrilateral whose vertices all lie on a single circle. Review terminology related to angles of a circle (e.g., central angle, inscribed angle, intercepted arc, and center) and the definitions and theorems that describe angle. A quadrilateral inscribed in a circle (also called cyclic quadrilateral) is a quadrilateral with four vertices on the circumference of a circle. Recall that an inscribed (or 'cyclic') quadrilateral is one where the four vertices all lie on a circle. Learn vocabulary, terms and more with flashcards, games and other study tools.
