What does SSS stand for in triangle congruence?

Back

Side-Side-Side: A method to prove triangles congruent by showing that all three sides are equal.

Front

Which triangle congruence rule is not valid?

Back

SSA (Side-Side-Angle) is not a valid rule for proving triangle congruence.

Front

If two angles of one triangle are equal to two angles of another triangle, what can be concluded?

Back

The triangles are similar, but not necessarily congruent.

Front

What is the significance of the included angle in SAS?

Back

The included angle is the angle between the two sides being compared, which is crucial for proving congruence.

Front

Can AAA be used to prove triangle congruence?

Back

No, AAA (Angle-Angle-Angle) can only prove similarity, not congruence.
