WebAngle = (11 × 360°)/ (2 × 22/7 × 7) Angle = 90°. Therefore, the angle of the arc is 90°. Example 2: Find the missing angle x in the diagram below. Solution: We need to find the value of x. One angle is given as 80°. By inscribed angle theorem we know that the central angle = 2 × inscribed angle. x = 2 × 80. WebTheorem 1. The first theorem about a cyclic quadrilateral state that: The opposite angles in a cyclic quadrilateral are supplementary. i.e., the sum of the opposite angles is equal to 180˚. Consider the diagram below. If a, b, c, and d are the inscribed quadrilateral’s internal angles, then. a + b = 180˚ and c + d = 180˚.
