What is the HL theorem in triangle congruence?

Back

Hypotenuse-Leg: In right triangles, if the hypotenuse and one leg are equal to another right triangle, then the triangles are congruent.

When can you use the ASA postulate?

Back

You can use the ASA postulate when you know two angles and the included side of one triangle are equal to the corresponding parts of another triangle.
