TANGENT AND SECANT PROOFS AND PRACTICE COMMON CORE GEOMETRY HOMEWORK Most of this homework set is designed to give you more practice with the angle/arc theorems. Only, the last problem is a derivation. PROBLEM SOLVING 1. In circle C shown below, a tangent has been drawn at point A. If m/CBA=28 , then explain why the measure of ZDAB must equal 62. 28 B In the circle shown, secants PE and PF have been drawn such that mCE =82 , mDF =98 and the ratio of mCD to mEF is 2:7. Determine the measure of ZP. Show how you arrived at your answer. E x C D F 98
