Question

Geometry. PLEASE help. Find the flaw in the proof. I'll give a medal.

Answer 1

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?
The measure of angle ZRY equals 180° by definition of supplementary angles.

Angles QRY and PQR should be proven congruent before the construction of line ZY.

The three angles of ΔPQR equal 180° according to Substitution.

Line ZY should be drawn parallel to segment QR.

Answer 10

I think it's C?

Answer 11

I do not know sorry @robtobey

Answer 12

It's ok

Answer 13

geometry proofs, never was my strong suit

Answer 14

it might help to actually follow the instruction given in the proof to see which ones just doesnt make sense to you

Answer 15

That worked well. C was right.

Answer 16

yay!!
