Review

It is not necessary to know all 6 parts are congruent for the triangles to be congruent. List below are 5 shorter ways to prove the triangles are congruent .

SSS

Side-Side-Side If the sides of one triangle are congruent to a second triangle then the triangles are congruent.

*

SAS Side-Angle-Side If two sides and the included angle of one triangle are congruent to a second triangle then the triangles are congruent

Be careful!

RB is not an included angle. This is not an example of SAS.

Day 4  Notes 4­4 & 4­5

ASA Angle-Side-Angle If two angles and the included side of one triangle are congruent to a second triangle then the triangles are congruent

AAS

* *

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

*

HL Hypotenuse-Leg If the hypotenuse and leg of one right triangle are congruent to a second right triangle then the triangles are congruent
