This is a discovery lesson concerning the Pythagorean Theorem. Students draw squares and calculate their area. Some of the squares have diagonal elements for their sides. To calculate their areas, it is necessary to divide the squares up into triangular pieces. Later students discover the Pythagorean relationship. It’s an interesting and effective-seeming idea. The author of this lesson has used it successfully.

Information - Discovering the Pythagorean Theorem
This is a packet where students will discover, using the areas of a square and triangle, the formula for Pythagorean Theorem.
On this worksheet students will use the triangles 1 and 2 pages to fill in a table with data and form their formula for Pythagorean Theorem. There are also questions to answer to guide them to the formula and problems to complete once they have formed the formula.
There is only one triangle on this sheet and it is not a right triangle. This helps the students understand that the Pythagorean Theorem only works with right triangles and allows for discussion on why they think this is true.
