Mod 12 - Pythagorean Theorem Review

What is the Pythagorean Theorem?

• a² + b² = c²

• a + b = c

• a - b = c

• a² + b³ = c⁴

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse
• scalene
• isosceles
• right

Side a on a right triangle is ALWAYS the longest side.

• true
• false

Side c on a right triangle is ALWAYS the longest.

• true

• false

What is the opposite of squaring a number?

• divide
• multiply 
• fractions
• square root

If a right triangle has side lengths 6, 6.7 and 3, which side is the hypotenuse?

• 6

• 6.7

• 3

• 15.7

Which equation could be used to solve to find the length of the missing side of the right triangle?

• 2² + 5² = x²

• x² + 2² = 5²

• x² + 5² = 2²

• 2 + 5 = x

Which equation could be used to solve to find the length of the missing side of the right triangle?

• 2.7² + 6.5² = x²

• x² + 2.7² = 6.5²

• x² + 6.5² = 2.7²

• 2.7 + x = 6.5
