WebThe first circle theorem we’re going to use here is: Rule 3, the angle at the centre is twice the angle at the circumference. The angle at the centre is 126\degree 126°, so; \angle BAD = 126\degree \div 2 = 63\degree ∠B AD = 126° ÷ 2 = 63°. We now know two out of the four angles inside ABCD AB C D. WebThe hypotenuses (OA and OB) are the same, as they are both the radius of the circle. OM is common to both triangles. OMA and OMB are both right angles. Triangles OAM and OBM are congruent (RHS ...
