es Proficiency in dealing with secants, tangents, and their associated angles requires a firm grasp of the fundamental theorems and formulas. Recognizing how angles are formed—whether outside or inside t
as long as they originate from the same external point. Angles Made by Two Tangents When two tangents are drawn from a common external point, they form an angle outside the circle. Key Theorem: > The measure of the angle between two tangent
ures of arcs are known or can be calculated. Angles Formed by a Tangent and a Secant Intersecting Inside the Circle Another interesting case occurs when a tangent and a secant intersect inside the circle, crea
