Pythagorean Theorem Quiz

The Pythagorean Theorem ONLY works on which triangle?

• obtuse

• scalene

• isosceles

• right

Draw a right triangle

Sides a and b are called legs.

• true

• false

Draw a right triangle and label the legs "a" and "b"

Side c on a right triangle is ALWAYS the longest.

• true

• false

Draw right triangle and label the hypotenuse "c"

Which side is the hypotenuse?

• a
• b
• c

What is the Pythagorean Theorem?

• a² + c² = b²

• a² + b² = c²

• c² + b² = a²

• b²- a² = c²

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

• The answer is c = 25

What is the length of the missing side of the following right angle triangle?
