Congruent & Similar Triangles Practice

Front

What is the definition of congruent triangles?

Back

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

Front

What is the definition of similar triangles?

Back

Triangles that have the same shape but not necessarily the same size; their corresponding angles are equal and their corresponding sides are proportional.

Front

What does the SAS congruence theorem state?

Back

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

Front

What does the SSS congruence theorem state?

Back

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

Front

What does the AAS congruence theorem state?

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 the ASA congruence theorem state?

Back

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

Front

What does the HL theorem state?

Back

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

Front

What is the SSS similarity postulate?

Back

If the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

Front

What is the AA similarity postulate?

Back

If two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What is the definition of corresponding sides in triangles?

Back

Sides that are in the same relative position in two different triangles.
