What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence stating that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What must be true if △ABC is congruent to △DEF by SSS?

Back

All corresponding sides and angles are equal: AB = DE, AC = DF, BC = EF, and ∠A = ∠D, ∠B = ∠E, ∠C = ∠F.

Front

What can be said about the corresponding sides of two congruent triangles?

Back

The corresponding sides of two congruent triangles are equal in length.

Front

If △ABC is congruent to △DEF, which angles are congruent?

Back

∠A is congruent to ∠D, ∠B is congruent to ∠E, and ∠C is congruent to ∠F.

Front

What is the definition of congruence in terms of rigid motions?

Back

Two figures are congruent if one can be transformed into the other through a series of rigid motions (translations, rotations, reflections).

Front

How many pairs of corresponding sides are congruent in two congruent triangles?

Back

Three pairs of corresponding sides are congruent.

Front

What is the relationship between congruence and similarity?

Back

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

Front

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

Back

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 Side-Angle-Side (SAS) criterion for triangle congruence?

Back

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 Hypotenuse-Leg (HL) theorem?

Back

In right triangles, if the hypotenuse and one leg of one triangle are equal to the hypotenuse and one leg of another triangle, the triangles are congruent.
