Below is to complete the question above:

Adam’s proof: angle 1 + angle 2 + angle 3 + angle 4 = 360°
                          Therefore, angle 2 + angle 3 = 180°
                         Hence, angle 1 = angle 3

Darius’ proof: angle 1 + angle 4 = 180° (transversal t is a straight line)
                         angle 1 + angle 2 = 180° (PQ is a straight line segment)
                         Therefore, angle 1 + angle 2 = angle 1 + angle 4
                          Hence, angle 2 = angle 4

Choices are

    Only Adam’s proof is correct.
    Only Darius’ proof is correct.
    Both Adam’s and Darius’ proofs are correct.
    Both Adam’s and Darius’ proofs are incorrect.

Answer is Adam's conclusion that angle 2 plus angle 3 is 180 is true, but unsupported. Further, the final conclusion is unsupported. Darius' proof is correct.

Answer:

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)

Step-by-step explanation:

Darius' Proof is correct, as he correctly defines the transitive property of equality. Unlike Adam, who falsely uses the term.
