Please help! 50 points and Brainliest! Below is a two-column proof incorrectly proving that the three angles of ΔPQR sum to 180°: Statements Reasons Draw line ZY parallel to segment QR Construction m∠ ZRP + m∠ PRQ + m∠ QRY = m∠ ZRY Angle Addition Postulate ∠ ZRP ≅ ∠ RPQ Alternate Interior Angles Theorem ∠ QRY ≅ ∠ PQR Alternate Interior Angles Theorem m∠ RPQ + m∠ PRQ + m∠ PQR = m∠ ZRY Substitution m∠ ZRY = 180° Definition of a Straight Angle m∠ RPQ + m∠ PRQ + m∠ PQR = 180° Substitution Which statement will accurately correct the two-column proof? (5 points) A) The measure of angle ZRY equals 180° by definition of supplementary angles. B) Angles QRY and PQR should be proven congruent before the construction of line ZY. C) The three angles of ΔPQR equal 180° according to the Transitive Property of Equality. D) Line ZY should be drawn parallel to segment PQ.
