Unit 5 Test (Similarity)

Front

What is AA Similarity in triangles?

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 is SSS Similarity in triangles?

Back

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

Front

What is SAS Similarity in triangles?

Back

SAS Similarity states that if two sides of one triangle are proportional to two sides of another triangle and the included angle is equal, then the triangles are similar.

Front

How do you determine if two triangles are similar?

Back

You can determine if two triangles are similar by checking for AA, SSS, or SAS similarity.

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the lengths of corresponding sides of the original figure to the dilated figure.

Front

If a triangle has sides of lengths 3, 4, and 5, what are the lengths of the sides of a triangle similar to it with a scale factor of 2?

Back

The lengths of the sides would be 6, 8, and 10.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position in different triangles when the triangles are similar.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines cross. They are always equal.

Front

What is the perimeter of a similar figure?

Back

The perimeter of a similar figure can be found by multiplying the perimeter of the original figure by the scale factor.
