Question

Joel and Melinda provide the following proofs for vertical angles to be equal.


Joel's proof: angle 2 + angle 3=180° (t is a straight line)
angle 1 + angle 2 = 180° (PQ is a straight line)
Therefore, angle 1 + angle 2 = angle 2 + angle 3 (Transitive Property of Equality)
Hence, angle 1 = angle 3 (Subtraction Property of Equality)

Melinda's proof: angle 1 + angle 2 + angle 3 + angle 4 = 360°
Therefore, angle 1 + angle 4 = 180° (t is a straight line)
Hence, angle 4 = angle 2 (Transitive Property of Equality)
Which statement is correct? (4 points)

Only Joel's proof is correct.
Only Melinda's proof is correct.
Both Joel's and Melinda's proofs are correct.
Both Joel's and Melinda's proofs are incorrect.

Answer 2

I thinK C

Answer 3

I know Melinda's proof is correct so I would probably go with B or C... you think C I would agree but just in case check again

Answer 4

go with C

Answer 5

yeah im pretty sure its C @TGstudios thanks
