Math 2 Unit 2 Midterm Review

Front

What is the definition of similar triangles?

Back

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

Front

What does AA Similarity mean?

Back

AA Similarity states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What does SAS Similarity mean?

Back

SAS Similarity 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 does SSS Similarity mean?

Back

SSS Similarity states that if the three sides of one triangle are in proportion to the three sides of another triangle, then the triangles are similar.

Front

How do you find the length of a side in similar triangles?

Back

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

Front

If triangle ABC is similar to triangle DEF, and the lengths of sides AB and DE are 4 and 8 respectively, what is the ratio of their corresponding sides?

Back

The ratio of the corresponding sides is 1:2.

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-Angle-Side (SAS) criterion for triangle similarity?

Back

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

Front

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

Back

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

Front

If two triangles have angles measuring 30°, 60°, and 90°, are they similar?

Back

Yes, they are similar by AA Similarity.
