The figures in each pair are similar. Write and solve a
proportion to find the length of each missing side.
- Rex draws two similar trapezoids
with the longer bases 12 cm and
15 cm in length. If the length of the
shorter base of the smaller trapezoid
is 4 cm, how long is the shorter base
of the larger trapezoid? - ABCDGF. AC, AB, and DF
are 3 cm, 5 cm, and 9 cm long,
respectively. How many times the
length of CBis the length of FG?

- Danielle draws two triangles. The first
triangle has sides that are 7, 10, and
13 inches long. The second triangle has
sides that are 10.5, 15, and 19.5 inches
long. Are the triangles similar? Explain. - The lengths, in inches, of the sides of a
triangle are 5, 8, and 11. If the shortest
side of a similar triangle has a length of
10 inches, what is the length of its
longest side?
