In the given figure, $\overline{\mathrm{MN}}\cong \overline{\mathrm{RS}},$ $\overline{\mathrm{MP}}\cong \overline{\mathrm{RO}},$ and $\overline{\mathrm{NO}}\cong \overline{\mathrm{PS}}.$
Prove that $\mathrm{\Delta NMP}\cong \mathrm{\Delta SRO}.$

When dealing with overlapping triangles, it may help to separate them.
