## Elementary Geometry for College Students (5th Edition)

To prove triangles congruent, use method SSS for the following pairs: 1) $\overline{MN}\cong\overline{MQ}$ 2) $\overline{PN}\cong\overline{PQ}$ 3) $\overline{MP}\cong\overline{MP}$
Here we have 1) $\overline{MN}\cong\overline{MQ}$ 2) $\overline{PN}\cong\overline{PQ}$ 3) $\overline{MP}\cong\overline{MP}$ So 3 sides of $\triangle MNP$ are congruent with 3 sides of $\triangle MQP$. That means $\triangle MNP\cong\triangle MQP$ according to SSS.
