Circle Theorems - Explanation with Solved Examples

Webwhere r is the radius of the circle, and d is the distance between the center of the circle and the intersection point S. This property follows directly from applying the chord theorem to a third chord going through S and the circle's center M (see drawing). The theorem can be proven using similar triangles (via the inscribed-angle theorem). WebThe angle at the centre of a circle is twice any angle at the circumference subtended by the same arc. The following diagrams illustrates the Inscribed Angle Theorem. Example: The center of the following circle is O. BOD is a diameter of the circle. Find the value of x. Solution: ∠BOC + 70˚ = 180˚ ∠BOC= 110˚ 2x = 110˚ x = × 110˚ = 55˚ grant woods food plot system
