On maths circle theorems
WebCircle Theorem 1 Proof, Ben Cairns, StudySmarter. Looking at the largest triangle, we know that 2x + 2y = 180 ° as the angles must sum to 180 °. As 2x + 2y = 180 °, it follows – by dividing by two – that x + y = 90 °. The angle at the circumference is given by x + y, and thus, the angle is right-angled. QED.

WebCircle theorems refer to the various rules relating to angles and circles. For example, the angles in semicircles are right angles, the opposing angles in a quadrilateral will always total 180° and the angles in the same segment of a circle are always equal.
