## Grade 8 Math: Pythagorean Theorem, Part 1

In this topic, the student learns the Pythagorean Theorem. This series of six lessons teaches the student many fundamental principles of the Pythagorean Theorem. The student first sees the Pythagorean Theorem being verified by measuring the sides of a right triangle. The student then uses the Pythagorean Theorem to find the missing side of a right triangle. The student also learns the distance formula.

This series of lessons develops the students mathematical capabilities through the use of geometry.

### Pythagorean Theorem: Verify by Measurement

This lesson teaches the student the Pythagorean Theorem. It also demonstrates how to verify the Pythagorean Theorem by measuring the sides of a right triangle.

### Pythagorean Theorem: Find the Missing Side

This lesson teaches the student to use the Pythagorean Theorem to find the length of the missing side of a right triangle. The lesson instructs finding the hypotenuse if it is not given, as well as finding the length of one of the legs if the lengths of the other leg and the hypotenuse are given.

### Pythagorean Theorem with Real Numbers

This lesson teaches the student how to find and approximate the value of unknown sides in a right triangle using the Pythagorean Theorem when the result is not a whole number. The lesson begins by explaining Pythagorean triples. It follows by showing how even if the unknown length doesnâ€™t complete a Pythagorean triple the side can still be solved for and approximated.
