Corresponding Sides and Angles

Front

What are corresponding sides in similar triangles?

Back

Corresponding sides are the sides of two or more triangles that are in the same relative position. In similar triangles, the lengths of corresponding sides are proportional.

What are corresponding angles in similar triangles?

Back

Corresponding angles are the angles in two or more triangles that are in the same relative position. In similar triangles, corresponding angles are equal.

How do you determine which angle corresponds to a given angle in similar triangles?

Back

To determine the corresponding angle, identify the position of the given angle in its triangle and find the angle in the other triangle that is in the same position.

What is the significance of the AA criterion for similarity?

Back

The AA (Angle-Angle) criterion states that if two angles of one triangle are equal to two angles of another triangle, the triangles are similar.
