Tell whether the two figures are similar. Explain your reasoning. (Hint: are they proportional?)

• Yes, similar because they are the same shape and side lengths are proportional.
• No, not similar because they are the same shape, but side lengths are not proportional.
• Yes, same shape
• No, different sizes

Read the problem and find the missing measurement.  Use labels or pictures to help set up the problem.
A home's height is 40 ft. and casts a shadow that is 12 ft..  A car in the driveway is 10 ft. high.  How long is the car's shadow?

• x = 3 ft.
• x = 12 ft.
• x = 120 ft.
• none of the above
