Right angles in a circle

WebIn a circle, the sum of the minor and major segment’s central angle is equal to 360 degrees. On the other hand, an inscribed angle is formed between two chords whose vertex lies in a … WebExample 2: Consider the circle given below with center O. Find the angle x using the circle theorems. Solution: Using the circle theorem 'The angle subtended by the diameter at the circumference is a right angle.', we have ∠ABC = 90°. So, using the triangle sum theorem, ∠BAC + ∠ACB + ∠ABC = 180° ⇒ x + 55° + 90° = 180° ⇒ x + 145° = 180°
