Question

One more proof question!

Answer 1

You already know <1 and <4 are congruent by given. so to prove their measures are equal what do you think the answer would be?

Answer 2

I think it's D. But, let me prove it myself.

Answer 3

@goformit100 it isnt D

Answer 4

Would it be the right angle congruence theorem? Since the given states that <1 and <2 are complementary, so are <3 and <4 so that means <1 and <4 are 90 degree right angles. And if they're congruent, that would make it C?

Answer 5

Okay.

Answer 6

yep!! @esshotwired is correct ... it isn't D

Answer 7

No since you already know they are congruent, the answer would have definition in it. You would say it to yourself: Since they are congruent, their measures are equal because of definiton of...

Answer 8

congruent! ahh I see. A then
thank you @esshotwired!!

Answer 9

your welcome :)
