Plz help. 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?

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.
