Understanding the Pythagorean Theorem

What is the Pythagorean theorem used for?

• Finding the length of sides in a right triangle

• Calculating the area of a circle

• Determining the volume of a cube

• Measuring the circumference of a square

In the Pythagorean theorem, what does 'c' represent?

• The length of the hypotenuse

• The length of one of the legs

• The perimeter of the triangle

• The area of the triangle

If the hypotenuse is 8.75 and one leg is 5.25, what is the length of the other leg?

• 9

• 8

• 7

• 6

What is the first step in finding a missing side using the Pythagorean theorem?

• Multiply the lengths of the known sides

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

• Add the squares of the known sides

• Divide the hypotenuse by one of the legs

What should you do after finding b² in the Pythagorean theorem?

• Subtract it from c²

• Multiply it by c

• Add it to a²

• Take the square root of b²
