Unit 6: Similar Triangles Review

Front

What are similar triangles?

Back

Triangles that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is the Angle-Angle (AA) criterion for triangle similarity?

Back

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

Front

What is the Side-Side-Side (SSS) criterion for triangle similarity?

Back

If the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the Side-Angle-Side (SAS) criterion for triangle similarity?

Back

If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are in proportion, then the triangles are similar.

Front

How do you solve for x in a proportion?

Back

Cross-multiply the terms and solve the resulting equation.

Front

What is a ratio?

Back

A ratio is a comparison of two quantities, showing how many times one value contains or is contained within the other.

Front

How do you simplify a ratio?

Back

Divide both terms of the ratio by their greatest common divisor (GCD).

Front

What is the formula for finding the ratio of two quantities?

Back

Front

How do you express a ratio in simplest form?

Back

By dividing both parts of the ratio by their greatest common factor.

Front

What is the relationship between similar triangles and proportions?

Back

In similar triangles, the ratios of the lengths of corresponding sides are equal.
