Assume a $\Delta SRQ$, where point N is the midpoint of SR and point M is the midpoint of SQ. Lines MR and NQ intersect at point P.
Is $\Delta MNP$ similar to $\Delta RQP$ ? I know that $\angle MPN$ and $\angle QPR$ are congruent, and that sides MN and QR are proportional, but that's only SA ... am I missing another side?
Thanks for the help!
