6. Which set of three numbers can be used
to make a right triangle?
1. What is the length of the hypotenuse of
the triangle below?

triangle using lengths of 10 feet, 60 feet,
and 65 feet?

are 10 inches long. How long is the
hypotenuse?
A 10 in.
C 20 in.
B 14.1 in.
D 28.2 in.
A 35.3
C 47
B 37
D 54.1
9. What is the distance between points W
and X to the nearest hundredth?
Use this figure for 4 and 5.

12. Dilate A′B′C′D′ by a scale factor of
9. No, they are not similar because only
one angle of the triangles is congruent.
The angle measures in the triangle at left
are 46°, 90°, and 44°. In the triangle at
right, the angle measures are 46°, 38°,
and 96°.

13. It is smaller than the original figure
because the scale factor is less
than 1.
14. Check students’ triangles and images.
10. No, it is not a function because there are
two different outputs (6 and 14) for the
same input (12).

15. No. The angle measures for the triangle
on the left are 60°, 62°, and 58°. The
angle measures for the triangle on the
right are 62°, 62°, and 56°. The triangles
have only one pair of congruent angles
so they are not similar.

11. No, the triangles have only one congruent
angle so they are not similar. The angles
of the left triangle measure 60°, 58°, and
62°. The angles of the right triangle
measure 60°, 59°, and 61°.

227.14 ÷ 27.04 = 8.4
The height is about 8.4 inches.
15. Yes. The lengths 3, 4, and 5 make a right
triangle because 32 + 42 = 52.

13. Two cylinders with the same diameter
may or may not have the same volume,
depending on the two heights. The same
is true for two cones. Two spheres with
the same diameter will have the same
volume because the formula doesn’t use
any other dimension.
17. EF = 6, FG = 8, EG = 10
14. No, 202 + 482 ≠ 542, so it cannot be a
right triangle.
