To find the height of a very tall pine tree, you place a mirror on the ground and stand where you can see the top of the pine tree. This creates similar triangles. How tall is the tree?

• 144 feet
• 72 feet
• 36 feet

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
