Question

Below is a two-column proof incorrectly proving that the three angles of ΔPQR sum to 180°:


Statements - Reason
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 Supplementary Angles
m∠RPQ + m∠PRQ + m∠PQR = 180° - Substitution


Which statement will accurately correct the two-column proof?
Which statement will accurately correct the two-column proof?
The measure of angle ZRY equals 180° by definition of supplementary angles.
Angles QRY and PQR should be proven congruent after the construction of line ZY.
The three angles of ΔPQR equal 180° according to the Transitive Property of Equality.
Line ZY should be drawn parallel to segment QR.
