Pythagorean Basics

The longest side of a right triangle is called the...

• leg A

• leg B

• hypotenuse

you ADD a² and b² then take the square root to find c on a right triangle.

• true

• false

Is this a right triangle?

• whatever that means

• no

• yes

The Pythagorean theorem states that:

• The two smaller sides of a right triangle sum to equal the longest side.

• The squares of the two smaller sides of a right triangle sum to equal the square of the longest side.

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 formula for finding the hypotenuse?

• a²⁺b²=c²

• a+b=c

• a-b=c

• c-a=c

solve for x

• 5552363959656.

• 10

• 100

• 89

The Pythagorean Theorem ONLY works on which triangle? 

• obtuse

• scalene

• isosceles

• right

Do the lengths form a right triangle? 6, 8, 10

• yes

• no

What is the relationship between the sides in the Pythagorean Theorem shown?

• a + b = c

• a² + b² = c²

• a² – b² = c²

• a – b = c
