Understanding the Pythagorean Theorem

What is the Pythagorean Theorem used for in geometry?

• To measure the angles in a triangle

• To determine the volume of a cube

• To find the relationship between the sides of a right triangle

• To calculate the area of a circle

In a right triangle, which side is always the hypotenuse?

• The side opposite the smallest angle

• The side opposite the right angle

• The side adjacent to the right angle

• The longest side

In the first example, what is the value of X when using the Pythagorean Theorem?

• 49

• 25

• 24

• 576

When solving for a missing side in the second example, what is the final simplified form of the answer?

• 13

• 2√13

• √104

• 2√26

What method is used in the second example to simplify the square root of a non-perfect square?
