This lesson uses the Pythagorean Theorem for three different applications:

• finding the distance between two points in a coordinate plane,
• finding the length of a diagonal in a three-dimensional figure, and
• using the Converse of the Pythagorean Theorem to determine if a triangle is a right triangle.

This lesson includes a warm-up, minilesson with guided steps through the process, examples, class activities and a worksheet for homework. Answer keys included.

In addition to the lesson plan, a Performance Task is included (Pythagorean Theorem Stations) and a screencast for flipped classrooms or additional student support.

Both Word and pdf versions included in the zip folder.
