Webbangles. The theorems are explained briefly and may include an illustration. Some of the proofs of the theorems will be developed in the exercises. Theorem 5-E ... angle, ∠EAC, … In geometry, an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle subtended at a point on the circle by two given points on the circle. Equivalently, an inscribed angle is defined by two chords of the circle sharing an endpoint.
