4.3 Triangle Congruence by ASA and AAS You can prove that two triangles are congruent without having to show that all corresponding parts are congruent. –You will prove triangles congruent by using one pair of corresponding sides and two pairs of corresponding angles.

Angle-Side-Angle If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent. Included Side

Using ASA Which two triangles are congruent by ASA? Explain. Triangle SUV is congruent to triangle NEO.

Angle-Angle-Side If two angles and a nonincluded side of one triangle are congruent to two angles and a nonincluded side of another triangle, then the triangles are congruent.
