4-5 OTHER METHODS OF PROVING TRIANGLES CONGRUENT

THEOREM

AAS Angle-Angle-Side: If two angles and a NON-

INCLUDED side are cong., then the triangles are cong.

HL (90) Hypotenuse-Leg: If the hypotenuse and leg of

two RIGHT triangles are cong, then the triangles are cong.

Right Triangles

HL: Must have the Hyp and EITHER Leg How do you know which side is the

Hypotenuse? It’s across from the 90. Always the longest.

Usually the “diagonal”.
