Question

Really need help - been stuck on this for an hour now

Triangle ABC is similar to triangle PQR, as shown below:
http://prntscr.com/96826w

Which equation is correct?
c/a = q/r
c/b = a/r
b/q = a/p
c/q = a/r

Answer 1

If the triangles are similar, then the ratio between corresponding sides is the same.

\[\frac{ a }{ p }=\frac{ b }{ q }=\frac{ c }{ r }\]

Answer 2

I just worked out all the corresponding sides and all the answer choices according to the corresponding sides and I found not one correct answer.

Answer 3

b/q = a/p
a corresponds with p and b corresponds with q

Answer 4

it's really that simple? I made this way harder than it needed to be, apparently.

Answer 5

yeah, you just need to match the sides together. At most you may have to cross multiply to get the the exact mix they want.

Answer 6

I was looking for some sort of connection on whether each one was a base/side relationship and what have you. It apparently wasn't that hard.

Answer 7

Thanks.

Answer 8

I never thought of it that way. I guess that does work. I pretty much just match the letters.

Answer 9

you're welcome

Answer 10

Yeah, but doing it that way didn't get me an answer lol
Would you be able to help me on another question if I posted it? I've been stuck on this entire test all day long.
