Triangle Congruency: SSS SAS

Front

What does SSS stand for in triangle congruency?

Back

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

Front

What does SAS stand for in triangle congruency?

Back

SAS stands for Side-Angle-Side, a postulate that states if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is an included angle in a triangle?

Back

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

Front

True or False: Angle A is included between sides BC and CA.

Back

False

Front

Which angle is included between sides AB and AC?

Back

Angle A is included between sides AB and AC.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

What is the significance of the CBD postulate in triangle congruency?

Back

The CBD postulate states that if two angles and the non-included side of one triangle are equal to two angles and the non-included side of another triangle, then the triangles are congruent.

Front

What side is included between Angle Y and Angle Z?

Back

Side YZ is included between Angle Y and Angle Z.

Front

What side is included between Angle D and Angle E?

Back

Side DE is included between Angle D and Angle E.

Front

How can you determine if two triangles are congruent using SSS?

Back

To determine if two triangles are congruent using SSS, measure all three sides of both triangles. If all three sides of one triangle are equal to the corresponding sides of the other triangle, they are congruent.
