SSS and SAS

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 included side in a triangle?

Back

The included side is the side that lies between two angles in a triangle.

Front

True or False: The included angle is the angle formed by two sides of a triangle.

Back

True

Front

Which triangle congruence theorem is used when two sides and the included angle are known?

Back

SAS (Side-Angle-Side) theorem.

Front

Which triangle congruence theorem is used when all three sides are known?

Back

SSS (Side-Side-Side) theorem.

Front

If triangle ABC is congruent to triangle DEF, what can be said about their corresponding sides and angles?

Back

Their corresponding sides and angles are equal.

Front

What is the difference between SAS and AAS in triangle congruence?

Back

SAS requires two sides and the included angle, while AAS requires two angles and a non-included side.

Front

In triangle ABC, if angle A is 60 degrees and side BC is 5 cm, what information is needed to use SAS for congruence?

Back

You need the lengths of another side and the included angle.

Front

What is the significance of the order of letters in triangle congruence?

Back

The order of letters indicates which angles and sides correspond to each other in congruent triangles.
