What does the acronym ASA stand for in triangle congruency?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruency where two angles and the included side of one triangle are equal to two angles and the included side of another triangle.

What does the acronym AAS stand for in triangle congruency?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruency where two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle.

How can you determine if two triangles are congruent using the SSS criterion?

Back

The SSS criterion states that if all three sides of one triangle are equal to all three sides of another triangle, then the triangles are congruent.

What is the difference between congruent triangles and similar triangles?

Back

Congruent triangles are identical in size and shape, while similar triangles have the same shape but may differ in size (corresponding angles are equal, and corresponding sides are proportional).

What is the importance of the included angle in the SAS criterion?

Back

The included angle is crucial in the SAS criterion because it must be between the two sides being compared to establish congruency.
