Triangle Similarity Review

Front

What is the definition of similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

What is the significance of the AA criterion for triangle similarity?

Back

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

What is the SAS similarity criterion?

Back

The SAS similarity criterion states that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

How do you find the length of a side in similar triangles?

Back

To find the length of a side in similar triangles, set up a proportion using the lengths of the corresponding sides and solve for the unknown length.

What is a common ratio in the context of similar triangles?

Back

A common ratio is the ratio of the lengths of corresponding sides of similar triangles, which remains constant.

What does it mean if the ratios of corresponding sides are not equal?

Back

If the ratios of corresponding sides are not equal, then the triangles are not similar.
