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. WebLegacy Paper.
