Similarity Theorems

Give the appropriate theorem or postulate that can be used to prove the triangles similar:

*There are 2 choices here. You must choose BOTH!*

• AA Postulate

• ASA Postulate

• SSS Postulate

• SAS Postulate

Determine if the triangles are similar. If so, state a postulate or theorem to justify your statement.

• Similar, AA Postulate

• Similar, SSS Postulate

• Similar, SAS Postulate

• Not Similar

Are the triangles similar? If so, by what theorem?

• SSS

• SAS

• AA

• Not Similar

Tell whether the triangles are similar or not.

• No

• Yes, by AA~

• Yes, by SAS~

• Yes, by SSS~
