    Adam's proof: angle 1 + angle 2 + angle 3 + angle 4 = 360° Therefore, angle 2 + angle 3 = 180° (t is a straight line) Hence, angle 1 = angle 3 (Transitive Property of Equality) Darius' proof: angle 1 + angle 4 = 180° (t is a straight line) angle 1 + angle 2 = 180° (PQ is a straight line) Therefore, angle 1 + angle 2 = angle 1 + angle 4 (Transitive Property of Equality) Hence, angle 2 = angle 4 (Subtraction Property of Equality) Which statement is correct? Only Adam's proof is correct. Both Adam's and Darius' proofs are correct. Both Adam's and Darius' proofs are incorrect. Only Darius' proof is correct.

    Adam's proof lacks something. He didn't state the reason "angle 1 + angle 2 + angle 3 + angle 4 = 360° ngle 1 + angle 2 + angle 3 + angle 4 = 360° ":)

    Anyway, great job! You just need a little practice and you'll realize that proving isn't that hard. :)
