What does SAS stand for?

Back

Side Angle Side

Front

Name the postulate that makes triangles congruent if two sides and the included angle are known.

Back

SAS

Front

Name the postulate that makes triangles congruent if all three sides are known.

SSS

Front

What is the included side in triangle DEF between angles D and E?

Back

Side DE

Front

If two triangles have two sides equal and the included angle equal, what can be concluded?

Back

The triangles are congruent by SAS.

Front

If two triangles have all three sides equal, what can be concluded?

Back

The triangles are congruent by SSS.

Front

What is the difference between SAS and SSS?

Back

SAS requires two sides and the included angle; SSS requires all three sides.

Front

Can SAS be used to prove congruence if only two sides are known?

Back

No, the included angle must also be known.

Front

If triangle ABC is congruent to triangle DEF by SSS, what can be said about their corresponding angles?

Back

Their corresponding angles are also equal.
