Unit 8, Lesson 11
Applications of the Pythagorean Theorem
Grade 8
Preparation
Lesson Narrative
This lesson gives students the opportunity to use the Pythagorean Theorem as a tool to solve different application problems (MP2). In the first activity, students make sense of a problem involving the distance and speed of two children walking and riding a bike along different sides of a triangular region. In the second activity they find internal diagonals of rectangular prisms.
By the end of this lesson, students should be ready to consider more complex problems involving the Pythagorean Theorem.
- Describe (orally) situations that use right triangles, and explain how the Pythagorean Theorem could help solve problems in those situations.
- Use the Pythagorean Theorem to solve problems within a context, and explain (orally) how to organize the reasoning.
Let’s explore some applications of the Pythagorean Theorem.
