Show conversely, a tangent to the circumference is perpendicularto the radius drawn to the point of contact. 2. Prove that the tangents to a circle at the… … Let; (J and O be the centres of two circumferences whichintersect each other at A and B, and let the line CC intersecttheir common chord at 0. To prove that CC is a perpendicular bisector of AB. Since A and B are points on both circles, they are equallydistant from C and also from C (by 127), the…
