G Unit 4B Test Review - Similarity

Front

What is the AA criterion for similarity?

Back

The AA criterion states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar (AA~).

Front

What does SAS similarity mean?

Back

SAS similarity means that 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 (SAS~).

Front

What is the SSS criterion for similarity?

Back

The SSS criterion states that if the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar (SSS~).

Front

How do you determine if two triangles are similar?

Back

To determine if two triangles are similar, check if they satisfy AA, SAS, or SSS criteria.

Front

What is a scale factor in similar triangles?

Back

A scale factor is the ratio of the lengths of corresponding sides of two similar triangles.

Front

If triangle ABC is similar to triangle DEF with a scale factor of 1/2, what is the relationship between their sides?

Back

The sides of triangle ABC are half the length of the corresponding sides of triangle DEF.

Front

If the scale factor from triangle DEF to triangle ABC is 2:1, what does this imply?

Back

This implies that the sides of triangle DEF are twice the length of the corresponding sides of triangle ABC.

Front

What does it mean if two lines are parallel in the context of triangles?

Back

If two lines are parallel, it can create similar triangles when a transversal intersects them.

Front

How can you prove that two triangles are not similar?

Back

You can prove that two triangles are not similar by showing that they do not meet the AA, SAS, or SSS criteria.

Front

What is the relationship between the angles of similar triangles?

Back

The corresponding angles of similar triangles are equal.
