(01.07 HC) Angie and Becky each completed a separate proof to show that the measures of vertical angles AKG and HKB are equal. Who completed the proof incorrectly? Explain. Angie's Proof K H Becky's Proof Statement 1. Segment GH intersects segment AB at K 1. Given 2. m/AKG+m/GKB = 180° mzGKB + m2HKB = 180° Justification 2. Definition of Supplementary Angles 3. mzAKG + mz GKB = mzGKB + m2HKB 3. Substitution Property 4. m/AKG = m/HKB 4. Subtraction Property
