What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle.

Front

What is the AAS criterion for triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruence where two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle.

Front

What is the SSS criterion for triangle congruence?

Back

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

Front

What is the SSA condition in triangle congruence?

Back

SSA stands for Side-Side-Angle, which is not a valid criterion for triangle congruence as it can lead to ambiguous cases.

Front

What is the HL theorem?

Back

The HL theorem states that if a triangle has a right angle, and the hypotenuse and one leg are congruent to the hypotenuse and one leg of another triangle, then the triangles are congruent.

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

What is the significance of the angle in the SAS criterion?

Back

In the SAS criterion, the angle must be the included angle between the two sides being compared.

Front

What is the relationship between congruent angles?

Back

Congruent angles have the same measure.

Front

What is the relationship between congruent sides?

Back

Congruent sides have the same length.

Front

What is the purpose of a proof in geometry?

Back

A proof in geometry is used to demonstrate the truth of a statement or theorem through logical reasoning and established facts.
