Pythagorean Theorem Quiz

What formula is used to find the length of the sides in a right triangle?

• A times B equals C squared

• A squared plus B squared equals C squared

• 2A plus 2B equals C

• A squared minus B squared equals C squared

If one leg of a right triangle is 6.7 feet and the other is 15.2 feet, what is the approximate length of the hypotenuse?

• 22.4 feet

• 16.6 feet

• 12.3 feet

• 18.9 feet

What is the first step in finding the missing leg of a right triangle when the lengths of the other leg and the hypotenuse are known?

• Square the length of the hypotenuse

• Add the squares of the known side lengths

• Multiply the lengths of the known side and hypotenuse

• Subtract the square of the known leg from the square of the hypotenuse

If the hypotenuse of a right triangle is 12.6 meters and one leg is 8.3 meters, what is the approximate length of the missing leg?

• 11.2 meters

• 4.3 meters

• 9.5 meters

• 10.7 meters

Why do we round the result when finding the length of a side in a right triangle using the Pythagorean theorem?

• To simplify the calculation process

• Because the square root of the sum can be an irrational number

• To make it easier to measure in real life

• Because the theorem only works with whole numbers
