John is trying to prove that the two triangles are similar. Put the steps in the order he would need to solve the problem.

• Look at the information given and determine whether to use SSS, SAS, or AA.

• Decide to use SSS.

• Match up the correct sides based on the similarity statement.

• Create 3 fractions and pair up the sides.

• Simplify the fractions to determine if they are similar.
