Select the correct answer form each drop-down menu. Given: m AOB = 42 m EOF = 66 Prove: m COD = 72 Three lines AD, CF, and BE are intersecting each other at the midpoint O Complete the proof. It is given that m AOB = 42 and m EOF = 66 . By the , EOF BOC . Therefore, m BOC = 66 . By the , m AOC = 108 , and by the , m AOC m COD = 180 . After application of the , m COD = 72
