Prove (using AAS) If 2 angles and a side not between them in one triangle are congruent to the corresponding two angles and side not between them in another triangle, then the triangles themselves are congruent.

PROOF In Exercises 19 and 20 , prove that the triangles are congruent using the AAS Congruence Theorem (Theorem 5.11 ). (See Example 3 .) Given $\quad \overline{\mathrm{VW}} \cong \overline{\mathrm{UW}}, \angle \mathrm{X} \cong \angle \mathrm{Z}$ Prove $\triangle \mathrm{XWVV} \cong \Delta \mathrm{ZWU}$

Proving Triangle Congruence by ASA and AAS
PROOF In Exercises 19 and 20 , prove that the triangles are congruent using the AAS Congruence Theorem (Theorem 5.11 ). (See Example 3 .) Given $\quad \angle \mathrm{NKM} \cong \angle \mathrm{LMK}, \angle \mathrm{L} \cong \angle \mathrm{N}$ Prove $\quad \Delta \mathrm{NMK} \cong \Delta \mathrm{LKM}$}$
