Congruent Triangles Practice

Front

What are congruent triangles?

Back

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

Front

What does the abbreviation 'HL' stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a method to prove the congruence of right triangles.

Front

What does 'SAS' mean in the context of triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle are equal.

Front

What does 'SSS' mean in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are equal to the three sides of another triangle.

Front

What does 'ASA' mean in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence where two angles and the included side are equal.

Front

What does 'AAS' mean in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruence where two angles and a non-included side are equal.

Front

If ∆ABC ≅ ∆DEF, what can we conclude about the angles?

Back

∠A ≅ ∠D, ∠B ≅ ∠E, ∠C ≅ ∠F.

Front

If two triangles have one equal angle and the sides adjacent to that angle are equal, what can be concluded?

Back

The triangles are congruent by the SAS criterion.

Front

What is the significance of corresponding parts in congruent triangles?

Back

Corresponding parts of congruent triangles are equal, which helps in proving triangle congruence.

Front

Can two triangles be congruent if only one angle is known?

Back

No, at least two angles or one angle and the included side must be known to prove congruence.
