Unit 2 Review--Final Exam

Front

What is the Side-Side-Side (SSS) Triangle Congruence Theorem?

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the Side-Angle-Side (SAS) Triangle Congruence Theorem?

Back

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 the Angle-Side-Angle (ASA) Triangle Congruence Theorem?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the Angle-Angle-Side (AAS) Triangle Congruence Theorem?

Back

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, then the triangles are congruent.

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

What is the definition of congruence in geometry?

Back

Congruence in geometry means that two figures have the same shape and size.

Front

What additional information is required for two triangles to be congruent by SSS?

Back

The lengths of all three sides of both triangles must be known.

Front

Can two triangles be congruent if only one angle is known?

Back

No, knowing only one angle is not sufficient to prove congruence; more information is needed.

Front

What is the difference between congruence and similarity?

Back

Congruent figures are identical in shape and size, while similar figures have the same shape but may differ in size.

Front

What is the purpose of the Triangle Congruence Theorems?

Back

They provide criteria to determine if two triangles are congruent based on their sides and angles.
