3rd: LT 8.4 SSS and SAS

Front

What does SSS stand for in triangle congruence?

Back

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

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a theorem stating that 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 does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a theorem stating that 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 does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a theorem stating that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are congruent.

Front

What is the included side in triangle ABC between angles A and C?

Back

The included side is side AC.

Front

What is the included angle between sides AB and AC in triangle ABC?

Back

The included angle is angle A.

Front

If two triangles have two sides of equal length and the angle between them is equal, what theorem can be used to prove they are congruent?

Back

The SAS (Side-Angle-Side) theorem can be used.

Front

In triangle XYZ, if side YZ is included between angles Y and Z, which side is it?

Back

Side YZ is the included side.

Front

If triangle ABC is congruent to triangle DEF by SAS, what does this imply about their corresponding parts?

Back

It implies that side AB is equal to side DE, side AC is equal to side DF, and angle A is equal to angle D.

Front

What is the significance of the included angle in triangle congruence?

Back

The included angle is crucial because it connects the two sides and helps establish congruence through the SAS theorem.
