Front

What does SSS stand for?

Back

Side-Side-Side

Front

What does SAS stand for?

Back

Side-Angle-Side

Front

What is the SAS triangle congruence criterion?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the SSS triangle congruence criterion?

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.
