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 AA similarity theorem?

Back

If two angles of one triangle are equal to two angles of another triangle, 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

What is the SSS similarity theorem?

Back

If the three sides of one triangle are in proportion to the three sides of another triangle, then the triangles are similar.

Front

What does it mean for triangles to be similar?

Back

It means that their corresponding angles are equal and their corresponding sides are proportional.

Front

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

Back

Set up a proportion comparing the lengths of corresponding sides and check if the ratios are equal.

Front

What is a proportion?

Back

A statement that two ratios are equal.

Front

If CB / DM = AC / ?, what is the missing side?

Back

AD.

Front

What is the Side Splitter Theorem?

Back

If a line is drawn parallel to one side of a triangle, it divides the other two sides proportionally.

Front

What is the significance of corresponding angles in similar triangles?

Back

Corresponding angles in similar triangles are equal, which is a key criterion for triangle similarity.
