Question

Can someone please confirm if i got the answer right??

Answer 1

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


Statements Reasons
∠QRY ≅ ∠PQR Alternate Interior Angles Theorem
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
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

Answer 2

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.

Answer 3

I say the answer is A: The measure of angle ZRY equals 180° by definition of supplementary angles.

Answer 4

Anyone agree or disagree?

Answer 5

Answer 6

oh ur a;ready here lol whoops

Answer 7

xD.. so i assume there is a graph of the figure?

Answer 8

i posted the question on top with my answer. And theres no graph

Answer 9

or maybe its B. a or b yeah?

Answer 10

The measure of angle ZRY equals 180° by definition of supplementary angles
is incorrect
it should be by definition of straight line of addition postulate
Now we eliminated Option A

Angles QRY and PQR should be proven congruent after the construction of line ZY.
They proved this even before constructing the line
So yeah B indeed

here's a proof
