Pythagorean Theorem Quiz

What is the Pythagorean Theorem?

• a² + c² = b²

• a² + b² = c²

• c² + b² = a²

• b²- a² = c²

What are the two shorter sides of a right triangle called?

• Hypotenuse

• Legs

• Bases

• Height

What is the longest side of a right triangle called?

• Legs

• Height

• Base

• Hypotenuse

TRUE OR FALSE : The Pythagorean Theorem applies ONLY if the triangle is a right triangle.

• True

• False

If a right triangle has side lengths 6, 6.7 and 3, which side would have to be the hypotenuse?

• 6

• 6.7

• 3

• None of them

For the following triangle, select ALL answers that are TRUE.

• c is the hypotenuse

• a and b are the legs

• c is a leg

• b is the longest side of the right triangle

• c is the longest side of the right triangle

What is the opposite of squaring a number?

• Multiplication

• Division

• Square Root

• Addition

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

What is the next step in solving this work for b?

a² + b² = c²

3² + b² = 12²

9 + b² = 144

• Add 144 and 9

• Subtract 9 from 144

• Take the square roots of 144 and 9
