Practice the Pythagorean Theorem
  • The base of a ladder is placed 6 feet from a wall. If the top of the ladder rests 8 feet up on the wall, how long is the ladder?

? feet

8 feet

a2 + b2 = c2

82 + 62 = c2

64 + 36 = c2

100 = c2

10 = c

6 feet

The length of the ladder is 10 feet.

  • Donna's TV screen is 20 inches long. If the diagonal measures 25 inches, how long is the width of Donna's TV?

? inches

25 inches

20 inches

a2 + b2 = c2

202 + b2 = 252

400 + b2 = 625

b2 = 225

b = 15

The width of the TV is 15 inches.

  • Town A is 9 miles north of Town B.Town C is 12 miles east of Town A.A road connects towns B and C directly. Find the length of this road.

Town C

Town A

12 miles

9 miles

? miles

Town B

a2 + b2 = c2

92 + 122 = c2

81 + 144= c2

225 = c2

15 = c

The length of the road is 15 miles.

  • If the legs of an isosceles right triangle are 5 inches long, find the length of the hypotenuse.

5 inches

5 inches

? inches

a2 + b2 = c2

52 + 52 = c2

25 + 25= c2

50 = c2
