Will give brainliest a conjecture and the flowchart proof used to prove the conjecture are shown. given: measure of angle d e g equals 51 degrees. measure of angle g e f equals 39 degrees. prove: triangle d e f is a right triangle. art: a right angle triangle d e f. angle d e f is a right angle. point g is on segment d f, and segment e g is drawn. drag an expression or phrase to each box to complete the proof.
