6.4 Similar Triangles

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 AA Similarity Postulate?

Back

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

Front

What is the SSS Similarity Theorem?

Back

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

Front

What is the SAS Similarity Theorem?

Back

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

How do you find the missing side in similar triangles?

Back

Use the proportion of the corresponding sides to set up a ratio and solve for the missing side.

Front

In similar polygons, what is true about corresponding sides?

Back

Corresponding sides are proportional.

Front

In similar polygons, what is true about corresponding angles?

Back

Corresponding angles are congruent.

Front

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

Back

Angle A = Angle D, Angle B = Angle E, Angle C = Angle F.

Front

What is a proportion?

Back

An equation that states that two ratios are equal.
