Triangle Congruence and Similarity

Front

What transformation creates similar figures?

Back

Dilation

Front

What does SSS stand for in triangle congruence?

Back

Side-Side-Side; if all three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent.

Front

What triangle congruence criteria is represented by two angles and the included side?

Back

ASA (Angle-Side-Angle)

Front

Which transformations create congruent figures?

Back

Translation, Reflection, Rotation

Front

What does ASA stand for in triangle congruence?

Back

Angle-Side-Angle; 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 does AAS stand for in triangle congruence?

Back

Angle-Angle-Side; if two angles and a non-included side of one triangle are equal to two angles and a corresponding non-included side of another triangle, the triangles are congruent.

Front

What is the criteria for triangle similarity based on corresponding angles?

Back

If two triangles have corresponding angles that are congruent, the triangles are similar.

Front

What does SSA stand for in triangle congruence?

Back

Side-Side-Angle; this is not a valid criterion for proving triangle congruence.

Front

What is the relationship between corresponding sides in similar triangles?

Back

Corresponding sides of similar triangles are proportional.

Front

What is the criteria for triangle similarity based on corresponding sides?

Back

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