What is the SAS congruence criterion?

Back

SAS stands for Side-Angle-Side, which states that 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.

What is the AAS congruence criterion?

Back

AAS stands for Angle-Angle-Side, which states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, which states that if all three sides of one triangle are equal to the three sides of another triangle, then the triangles are congruent.

What is the difference between congruence and similarity?

Back

Congruence means that two shapes are identical in size and shape, while similarity means that two shapes have the same shape but may differ in size.

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.
