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. line AB intersecting line GH at K Angie's Proof StatementJustification 1. Segment GH intersects segment AB at K1. Given 2. m∠AKG m∠GKB = 180° m∠GKB m∠HKB = 180°2. Definition of Supplementary Angles 3. m∠AKG m∠ GKB = m∠GKB m∠HKB3. Substitution Property 4. m∠AKG = m∠HKB4. Subtraction Property Becky's Proof StatementJustification 1. Segment GH intersects segment AB at K1. Given 2. m∠AKG m∠GKB = 180° m∠GKB m∠HKB = 180°2. Angle Addition Postulate 3. m∠AKG m∠ GKB = m∠GKB m∠HKB3. Substitution Property 4. m∠AKG = m∠HKB4.
