RETEST Unit 4B Triangle Similarity

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is the AA criterion for triangle similarity?

Back

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

Front

What is the SAS criterion for triangle similarity?

Back

The SAS (Side-Angle-Side) 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.

Front

What is the SSS criterion for triangle similarity?

Back

The SSS (Side-Side-Side) criterion states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

How do you set up a proportion for similar triangles?

Back

Front

If triangle ABC is similar to triangle WXY, what can be said about their angles?

Back

The corresponding angles of triangle ABC and triangle WXY are equal.

Front

If a 10-meter tall pole casts an 8-meter shadow, how can you find the height of a tree casting a 14-meter shadow?

Back

Front

What is the height of a tree if a 10-meter pole casts an 8-meter shadow and the tree casts a 14-meter shadow?

Back

The height of the tree is 17.5 meters.

Front

What is the formula for finding the height of similar triangles using shadows?

Back

Front

What does it mean if two triangles are not similar?

Back

If two triangles are not similar, it means that their corresponding angles are not equal or their corresponding sides are not in proportion.
