Front

What does it mean for two triangles to be congruent?

Back

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

Front

List the criteria for triangle congruence.

Back

SAS (Side-Angle-Side), SSS (Side-Side-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), and HL (Hypotenuse-Leg for right triangles).

Front

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

Back

The two triangles are congruent (AA criterion).

Front

What is the significance of corresponding parts in congruent triangles?

Back

Corresponding parts of congruent triangles are equal, which means if two triangles are congruent, all their corresponding sides and angles are equal.
