Janet is designing a frame for a client. She wants to prove to her client that m∠AGE ≅ m∠CHE in her sketch. What is the missing justification in the proof? Segment AB is parallel to segment CD, and transversal EF intersects segment AB at G and segment CD at H. Statement Justification segment AB is parallel to segment CD with transversal segment EF Given m∠AGE ≅ m∠HGB Vertical Angles Theorem m∠HGB ≅ m∠CHE Alternate Interior Angles Theorem m∠AGE ≅ m∠CHE
