Similar Sides and Proportions

The pair of figures is similar. Find the missing side.

• x = 10

• x = 4

• x = 2

• x = 5

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.  How tall is the tree? Hint: the figures are similar triangles.

• 8 feet

• 72 feet

• 36 feet

• 144 feet

Solve for X.

• 2 ft

• 3 ft

• 4 ft

• 6 ft

Review the picture. Find the missing side measurement in the picture using a proportion.

• x = 900 m

• x = 52 m

• x = 25 m

• x = 0.04 m

Tell whether the two figures are similar. Explain your reasoning.

• 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

• A
• B
• C
• D

Figure JKLM is similar to figure PQRS.

Which of the corresponding side ratios match for the figures that are shown above.
