Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

What is the criterion for triangle congruence if no sides or angles are equal?

Back

If no sides or angles are equal, the triangles are not congruent.

Front

If two triangles have two sides equal and the included angle is not equal, are they congruent?

Back

No, they are not congruent. The SAS criterion requires the included angle to be equal.

What is the importance of triangle congruence in geometry?

Back

Triangle congruence is important because it allows us to prove that two triangles are identical in shape and size, which is fundamental in solving geometric problems.
