We are asked to name the segment parallel to QR in the following image:
Notice that there are several segments parallel to QR:
MS is one, SN is another one, and the longer MN is another one.
If what you are asked to do is as well determine the measure of QR , then we have to use similar triangles. and the proportions between them. If that is the question as well, we mark segment QR with a SINGLE TICK (as MS and SN are marked.
