Test 1 - Congruent Triangles

Front

What are congruent triangles?

Back

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

Front

What is the symbol for congruence?

Back

The symbol for congruence is '≅'.

Front

What does the congruence statement ΔABC ≅ ΔXYZ indicate?

Back

It indicates that triangle ABC is congruent to triangle XYZ, meaning their corresponding sides and angles are equal.

Front

What are corresponding angles in congruent triangles?

Back

Angles in one triangle that match with angles in another triangle when the triangles are congruent.

Front

What are corresponding sides in congruent triangles?

Back

Sides in one triangle that match with sides in another triangle when the triangles are congruent.

Front

What is the Angle-Angle (AA) Congruence Postulate?

Back

If two angles of one triangle are congruent to two angles of another triangle, the triangles are congruent.

Front

What is the Side-Side-Side (SSS) Congruence Postulate?

Back

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

Front

What is the Side-Angle-Side (SAS) Congruence Postulate?

Back

If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the Angle-Side-Angle (ASA) Congruence Postulate?

Back

If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, the triangles are congruent.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always congruent.
