The figure below shows two triangles that were constructed using a compass and straightedge. Riley used the SAS postulate to prove that triangle PQR is congruent to triangle LMN. As part of the proof Riley showed that side PQ is congruent to side LM. Using this congruency, which of these other steps would Riley have likely performed to prove that the two triangles are congruent by the SAS postulate?

I'm getting an error when trying to open the link, can you draw out whatever was in the link?

Place the compass on P and draw an arc to cross side PR at X and side PQ at Y. Place the compass on X and set the width of the compass to segment XY. Place the compass on L and set the width to LM. Place the compass on L and draw an arc that passes through points N and M. Place the compass on R and draw an arc to cross side QR at X and side RP at Y. Place the compass on X and set the width of the compass to segment XY.
