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
ough the center of the circle. Arcs and Central Angles The measure of an arc is equal to the measure of its central angle. Minor arc measures are less than 180°, major arcs are greater than 180°. Practice Exercises to Master Tangents, Arcs, and Chords 1.
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
tangent segment equals the power of P with respect to the circle. Alternatively, draw the circle and point P; construct the two possible tangent lines using the point P and the circle's radius, verifying perpendicularity at the point of con
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
