SSS and SAS Practice Flashcard

Front

What does SSS stand for 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 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 equal to two sides and the included angle of another triangle.

Front

What is the ASA criterion for triangle congruence?

Back

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

Front

What does AAS stand for in 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 equal to two angles and the corresponding non-included side of another triangle.

Front

What is the significance of congruence statements in triangles?

Back

Congruence statements indicate that two triangles are congruent and provide a way to express which corresponding parts (sides and angles) are equal.

Front

If triangle ABC is congruent to triangle DEF, what can we say about their corresponding parts?

Back

If triangle ABC is congruent to triangle DEF, then AB = DE, BC = EF, AC = DF, and

Front

How can you prove triangles are congruent using the SSS criterion?

Back

To prove triangles are congruent using SSS, show that all three sides of one triangle are equal to the three sides of another triangle.

Front

What is the relationship between congruent angles in congruent triangles?

Back

In congruent triangles, corresponding angles are equal.

Front

If two triangles have two sides equal and the included angle equal, what can be concluded?

Back

The triangles are congruent by the SAS criterion.

Front

What is the purpose of using congruence criteria in geometry?

Back

Congruence criteria help determine if two triangles are congruent without needing to measure all sides and angles.
