Coach E's Triangle Similarity Practice

Front

If the triangles are similar, state how.

Back

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

Front

Given that the two triangles are similar, which side is corresponding to PQ?

Back

In similar triangles, corresponding sides are in proportion. If triangles are similar, the side corresponding to PQ is DE.

Front

Find the missing length indicated: 16, 8, 10, 14.

Back

The missing length is 10.

Front

In Similar figures the ________________ are the same.

Back

Angles are the same in similar figures.

Front

Find the missing length: 21, 18, 16, 24.

Back

The missing length is 21.

Front

What does SSS stand for in triangle similarity?

Back

SSS stands for Side-Side-Side similarity criterion, which states that if the sides of one triangle are proportional to the sides of another triangle, then the triangles are similar.

Front

What is the SAS similarity criterion?

Back

SAS stands for Side-Angle-Side similarity criterion, which states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.

Front

How do you determine if two triangles are similar using AA?

Back

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

Front

What is the significance of corresponding sides in similar triangles?

Back

Corresponding sides of similar triangles are in proportion, meaning the ratios of their lengths are equal.
