• x = 4

• x = 2

• x = 5

State if the triangles are similar by SSS.

• Yes, SSS Similarity

• Similiar but not SSS

• Not Similar

The Side-Angle-Side Similarity (SAS ~) Theorem states that if two sides of one triangle are ________________ to two sides of another triangle and their _________________ angles are congruent, then the triangles are similar.

• complementary; form

• adjacent; create

• proportional; included
