Triangle Congruence Mixed Practice (No HL)

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What does the acronym SAS stand for in triangle congruence?

Back

Side-Angle-Side; a method to prove triangles are congruent if two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.

Front

What is the Angle-Side-Angle (ASA) congruence criterion?

Back

If two angles and the side between them in one triangle are equal to two angles and the side between them in another triangle, the triangles are congruent.

Front

What is the Side-Side-Side (SSS) congruence criterion?

Back

If all three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent.

Front

What is the Angle-Angle (AA) similarity criterion?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar, but not necessarily congruent.

Front

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

Back

Measure all three sides of both triangles; if all three pairs of sides are equal, the triangles are congruent.

Front

What additional information is required for two triangles to be congruent by SAS?

Back

The lengths of two sides and the measure of the included angle must be known.

Front

What is the definition of corresponding parts in triangle congruence?

Back

Corresponding parts are the sides and angles of triangles that are in the same relative position.

Front

What is the purpose of a congruence statement?

Back

To indicate that two triangles are congruent and to show the correspondence between their parts.

Front

What is the definition of a triangle?

Back

A polygon with three edges and three vertices.
