M3: Similarity Unit Review

Front

What is the definition of similar figures?

Back

Two objects that are the same shape but not the same size are called similar figures.

Front

What does SSS~ stand for in similarity?

Back

SSS~ stands for Side-Side-Side similarity, which states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What does SAS~ stand for in similarity?

Back

SAS~ stands for Side-Angle-Side similarity, which 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

If two triangles are similar, what can be said about their angles?

Back

If two triangles are similar, their corresponding angles are equal.

Front

Solve for m: m² - 100 = 0

Back

m = 10, -10

Front

A power pole 10 m tall casts a shadow 8 m long. If a building casts a shadow 14 m long, how tall is the building?

Back

The building is 17.5 m tall.

Front

Can you use SSS~ or SAS~ without checking the ratios of the sides?

Back

False. You must check the ratios of the sides.

Front

What is the relationship between the sides of similar triangles?

Back

The corresponding sides of similar triangles are in proportion.

Front

If triangle ABC is similar to triangle DEF, what can be said about the lengths of their sides?

Back

The lengths of the sides of triangle ABC are proportional to the lengths of the sides of triangle DEF.

Front

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

Back

Height = (Length of shadow of object / Length of shadow of reference) * Height of reference.
