The objective of this activity is to practice calculating the length of the third side of a right triangle using Pythagorean's Theorem.

Materials: You will need a piece of paper and a pencil to record your work.

Procedure:

1. Pythagorean Theorem states that .
2. Given this, you are to calculate the length of the third side of a right triangle using Pythagorean's Theorem. Remember that side "c" is always the hypotenuse of the right triangle - the longest side of the right triangle.
3. In the Pythagorean Explorer, enter your choice of question - easy, medium, and hard.
4. A triangle will appear, calculate the length of the third side. Use the calculator above to assist in calculations.
5. In your notebook, record a drawing of the triangle. Label the side lengths and the unknown length. Show your calculations while you solve for "x" using Pythagorean's Theorem.
6. Enter the value in the Pythagorean Explorer answer box and check your work.
7. REPEAT steps 3-6 ten times. (You will have completed 10 Pythagorean explorer questions when you are done).
8. Save your answer sheet for your instructor.
