Three-D Pythagorean Theorem

Which set of side lengths would form a right triangle?

• 6, 9, 12

• 8, 10, 12

• 9, 40, 41

• 5, 10, 12

Which of these is closest to the length of PQ?

• 10.9 units

• 13 units

• 2.4 units

• 169 units

Please read the question carefully:

• A

• B

• C

• D

What is the final step in solving this work for c?
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
25 = c²

• Divide both sides by 2

• Take the square root of both sides
