SECANT TANGENT INTERSECT AT THE POINT OF TANGENCY
Activity: Find it out by Yourself!
Given: In the figure below, line QS is a secant and line RW is a tangent intersecting at S, the point of tangency. Arc QS is the intercepted arc of Angle QSR while Arc QTS is the intercepted arc of Angle QSW.
Move the point of tangency to observe the relationship of tangent and secant to its inscribed angle.
Question: Is there any relationship among the measure of angle QSR and arc QS? How about the measure of angle QSW and arc QW? Describe the relationship if there is any.
