Similar Triangles by AA Theorem

Determine if the triangles are similar. If they are, identify the triangle similarity theorem(s) that prove(s) the similarity.

• AA ~ Theorem

• SAS ~ Theorem

• SSS ~ Theorem

• Not similar

State the postulate that proves these triangles are similar.

• AA~

• SAS~

• SSS~

• AAS~

Are these triangles similar?

• No, they are not similar

• Not Enough Information 

• Yes, similar by AA~ 

Determine if the triangles are similar. If they are, identify the triangle similarity theorem(s) that prove(s) the similarity.

• SSS ~ Theorem

• Not similar

What similarity theorem would prove that these triangles are similar?

• SAS∼

• SSS∼

• AA∼

• Side Splitter

Are the triangles similar? If yes, choose which theorem we would use to prove similarity.

• AA~

• SSS~

• SAS~

• Not Similar

The triangles are similar. State the reason and complete the similarity statement.

Answer explanation

The order of the points matter! Make sure congruent angles are in the same place.
