Henry and Amy provide the following proofs for vertical angles to be equal: A line PQ is shown cut by a transversal t. 1, 2, 3, 4 are marked clockwise as the four angles formed by the transversal on the

Henry's proof: angle 2 + angle 3=180° (t is a straight line)

angle 1 + angle 2 = 180° (PQ is a straight line)

Therefore, angle 1 + angle 2 = angle 2 + angle 3 (Transitive Property of Equality)

Hence, angle 1 = angle 3 (Subtraction Property of Equality)

Amy's proof: angle 1 + angle 2 + angle 3 + angle 4 = 360°

Therefore, angle 1 + angle 4 = 180° (t is a straight line)

Hence, angle 4 = angle 2 (Transitive Property of Equality)
