WebTo prove the inscribed angle theorem we need to consider three cases: Inscribed angle is between a chord and the diameter of a circle. Diameter is between the rays of the inscribed angle. Diameter is outside the rays of the inscribed angle. Case 1. Inscribed angle is between a chord and the diameter of a circle. Here we need to prove that ∠AOB = 2θ Webtoo. The chords will all turn out to be equal because of the following theorem: Theorem 10.2 : If the angles subtended by the chords of a circle at the centre are equal, then the chords are equal. The above theorem is the converse of the Theorem 10.1. Note that in Fig. 10.13, if you take ∠ AOB = ∠ COD, then Δ AOB ≅ Δ COD (Why?)

Given : a circle with center O. AB is a chord of circle and OM bisects AB. To prove : ∠AOB = ∠DOC Proof : In AOB and COD OA = OD (Radius) OB = OC (Radius) AB = CD (Given) ⇒ AOB ⩭ COD (by SSS congruency) ∠AOB = ∠DOC ( By C.P.C.T. ) Hence proved. Share …
