Unit 3 Review: Dilations and Similarity

Front

What does SSS similarity mean?

Back

SSS similarity (Side-Side-Side) states that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What does SAS similarity mean?

Back

SAS similarity (Side-Angle-Side) 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 AA similarity mean?

Back

AA similarity (Angle-Angle) states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

State the similarity statement for triangles ACB and DFE if they are similar by SSS.

Back

Front

What is the criterion for determining if two triangles are similar?

Back

The criteria are SSS, SAS, and AA.

Front

If two triangles have one angle equal and the sides including that angle are in proportion, what can be concluded?

Back

The triangles are similar by SAS similarity.

Front

If two triangles have two angles equal, what can be concluded?

Back

The triangles are similar by AA similarity.

Front

What is the relationship between the ratios of corresponding sides of similar triangles?

Back

The ratios of corresponding sides of similar triangles are equal.

Front

If the corresponding angles of two triangles are not equal, what can be concluded about their similarity?

Back

The triangles are not similar.

Front

What is the significance of the similarity postulate in geometry?

Back

The similarity postulate helps to determine if two triangles are similar based on their angles and sides.
