Similar Congruent Triangles

Determine whether the triangles are similar by AA~, SSS~, SAS~, or not similar.

• AA

• SSS

• SAS

• no similar

Determine if the triangles are similar. Justify.

• Yes, by SSS.

• Yes, by SAS. Scale Factor is 1:2.

• Yes, by SAS. Scale Factor is 3:1.

• No, not similar.

Choose the similarity statement for the triangles.

• ΔMNL ∼ ΔOPQ

• ΔNOM ∼ ΔPQL

• ΔLMN ∼ ΔPQO

• ΔMLN ∼ ΔPQO
