WebTheorem 10.16 Angles Outside the Circle Theorem If a tangent and a secant, two tangents, or two secants intersect outside a circle, then the measure of the angle formed … WebSymbols If l∏ CB&*, then lis tangent to (C at B. THEOREMS 11.1 and 11.2 B C l B C l AC&*(is tangent to (B at point C. Find BC. Solution BC&*is a radius of (B, so you can apply Theorem 11.1 to conclude that BC&*and AC&*(are perpendicular. So, aBCA is a right angle, and TBCA is a right triangle. To find BC, use the Pythagorean Theorem. WebJun 30, 2013 · 21. Using properties of tangents • The point at which a tangent line intersects the circle to which it is tangent is called the point of tangency. You will justify theorems in the exercises. 22. l Q P Theorem 10.1 • If a line is tangent to a circle, then it is perpendicular to the radius drawn to the point of tangency. ground cleaning atlantis fl
