Question

For #2 – 7, state whether each is a property that shows congruence between two triangles using Yes or No. _____ 2. SSS_____ 5. SAS_____ 3. SSA_____ 6. ASA_____ 4. AAS_____ 7. AAA

Answer 1

In order to prove that two triangles are congruent, the following cases of congruency can be used:

SSS (all three sides congruent)

SAS (two sides and the angle between them congruent)

ASA (two angles and the side between them congruent)

AAS (two angles and the side not between them congruent)

The other cases (AAA and SSA) are not congruency theorems.
