What is the AAS criterion for triangle congruence?

Back

If two angles and the non-included side of one triangle are congruent to two angles and the non-included side of another triangle, the triangles are congruent.

What is the significance of vertical angles in triangle congruence?

Back

Vertical angles are always congruent, which can help in proving triangles congruent.

How can you prove triangles congruent using the SAS criterion?

Back

You need to show that two sides and the angle between them in one triangle are congruent to the corresponding parts in another triangle.
