## Activity One: Who is Pythagoras?

Target Objective:

- In an online discussion forum, students will be able to determine importance of Pythagoras in mathematical history by stating at least one of Pythagoras' accomplishments, and why this/these accomplishment(s) are the best.

Go to Who is Pythagoras?

## Activity Two: Proof Behind the Pythagorean Theorem

Target Objective:

- In a discussion group, the student will be able to justify the Pythagorean Theorem by explaining why the squares of the legs are equal to the square of the hypotenuse.

## Activity Three: Finding the Unknown Side of a Right Triangle using Pythagorean Theorem

Target Objective:

- Given two sides of a right triangle, students will be able to determine the length of the unknown side of the right triangle by using Pythagorean Theorem and a calculator.

Go to Finding the Unknown Side of a Right Triangle using Pythagorean Theorem

## Activity Four: Using Pythagorean Theorem to Solve Real World Problems

Target Objective:

- Given a scenario describing a right triangle, students will be able to draw a picture representing the passage, and solve for the missing distance by using Pythagorean Theorem and a calculator.

Go to Using Pythagorean Theorem to Solve Real World Problems

## Activity Five: Is it a triangle, a right triangle, or not a triangle?

Target Objective:

- Given three lengths, students will determine whether the lengths create a right triangle by applying the Pythagorean Theorem and using a calculator.

Go to Is it a triangle, a right triangle, or not a triangle?
