You need to apply the SAS Triangle Similarity Theorem to get the two triangles similar. http://www.regentsprep.org/regents/math/geometry/gp11/LsimilarProof.htm

I don't need the answer, just an explanation for the given. i am having a hard time understanding what it means...

anonymous · Answer

It's defining the lengths of the sides, so the length of side PR divided by the length of side MR is the same ratio as the length of side QR divided by side NR.  Does that make sense?

anonymous · Answer

Yes it does. Thanks!

directrix · Answer

Steps
----
1. PR/MR = QR/NR
2. <R is congruent to <R
3. Triangle PRQ ~ Triangle MRN
4. <1 is congruent to <2

You try to do the reasons, okay? @one2345
