Congruent Triangles

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal.

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side; a postulate that states if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the definition of congruent triangles?

Back

Triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

What is the SAS postulate?

Back

Side-Angle-Side; a postulate that states if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the ASA postulate?

Back

Angle-Side-Angle; a postulate that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is the AAS theorem?

Back

Angle-Angle-Side; a theorem that states 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, the triangles are congruent.

Front

What does HL stand for in triangle congruence?

Back

Hypotenuse-Leg; a theorem that applies to right triangles, stating that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.

Front

What are corresponding sides?

Back

Sides that are in the same position in two different triangles.

Front

True or False: All corresponding angles in congruent triangles are congruent.

Back

True

Front

If ∠A ≅ ∠M, what does this mean?

Back

Angle A is congruent to Angle M.
