Unit 5 Vocabulary

Front

Congruence Transformation

Back

A transformation that preserves the size and shape of a figure.

Front

Side-Side-Side Congruence

Back

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

Front

Side-Angle-Side Congruence

Back

If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.

Front

Angle-Angle-Side Congruence

Back

If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

Front

Angle-Side-Angle Congruence

Back

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

Front

Hypotenuse-Leg Congruence

Back

In right triangles, if the hypotenuse and one leg of one triangle are congruent to the hypotenuse and one leg of another triangle, then the triangles are congruent.

Front

Third Angle Theorem

Back

If two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.

Front

Triangle Inequality Conjecture

Back

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Front

Hinge Theorem

Back

If two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first is longer than the third side of the second.
