Congruent Triangles CFU

Front

What is a rigid motion in geometry?

Back

A rigid motion is a transformation that preserves size and shape.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a theorem that states 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 that states 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 that states 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 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

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

Back

To determine if two triangles are congruent using the SSS theorem, measure all three sides of both triangles and check if they are equal.

Front

How can you determine if two triangles are congruent using the SAS theorem?

Back

To determine if two triangles are congruent using the SAS theorem, measure two sides and the included angle of both triangles and check if they are equal.

Front

How can you determine if two triangles are congruent using the ASA theorem?

Back

To determine if two triangles are congruent using the ASA theorem, measure two angles and the included side of both triangles and check if they are equal.

Front

What is the significance of the included angle in the SAS theorem?

Back

The included angle is the angle formed between the two sides being measured; it must be equal for the triangles to be congruent.

Front

Can two triangles be congruent if only one side is equal?

Back

No, two triangles cannot be congruent if only one side is equal; at least two sides and the included angle must be equal.
