SSS SAS Warmup

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 is the included angle in a triangle?

Back

The included angle is the angle formed between two sides of a triangle.

Front

True or False: The angle between sides AB and AC is Angle A.

Back

True.

Front

Which triangle congruence theorem can be used if two sides and the included angle are known?

Back

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

Front

Which triangle congruence theorem can be used if all three sides are known?

Back

SSS (Side-Side-Side) theorem can be used.

Front

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

Back

ASA (Angle-Side-Angle) requires two angles and the included side, while AAS (Angle-Angle-Side) requires two angles and a non-included side.

Front

If two triangles have two angles equal, what can be said about their sides?

Back

The sides opposite those angles are proportional, and the triangles are similar.

Front

What is the significance of congruent triangles in geometry?

Back

Congruent triangles have the same size and shape, which means all corresponding sides and angles are equal.

Front

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

Back

By showing that all three corresponding sides of the triangles are equal in length.
