Tangent perpendicular to radius proof

WebJun 15, 2024 · Tangent to a Circle Theorem: A line is tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency. Figure is tangent at point if and only if . This theorem uses the words “if and only if,” making it a biconditional statement, which means the converse of this theorem is also true. 2. WebThe tangent point is the point A of the circle. The radius OA is drawn to the tangent point. The Theorem states that the radius OA is perpendicular to the tangent line AB, or, in other words, the angle OAB is the right angle. For the proof, let us assume that the angle OAB is not the right angle. Then, considering two adjacent angles to the ...
