Unit 8 Review Game

Determine whether the polygons are similar. Explain your reasoning.

• The scale factor is 3 for all sides, so yes.

• The scale factor is 1/3 for all sides, so yes.

• The scale factors do not match, so no.

• Not enough information.

Determine whether the polygons are similar. Explain your reasoning.

• No, the scale factors do not match.

• Yes, the scale factor is 5/3 for all sides.

• Yes, the scale factor is 3/5 for all sides.

• Not enough information.

• The scale factor is 5/2.

• The scale factor is 2/5.

• The scale factor does not match.

• Not enough information.

In the diagram, LMNO is similar to PQRS. MN/QR = LM/?

• MN/RQ = LM/PS

• MN/RQ = LM/PQ

• MN/RQ = LM/SR

• MN/RQ = LM/QR

Find the value of x. (Remember to hand in math work.)

Determine whether the triangles are similar. Explain your reasoning. (You should be telling me what is congruent or similar and what theorem you are using to prove that they are similar)
