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 PQ 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° Additive Property of Equality
Which statement will accurately correct the two-column proof?
(5 points)
Select one:
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 Substitution.
d. Line ZY should be drawn parallel to segment QR.
