This Discovering Triangle Sum lesson plan also includes:
Math is everywhere, even in bikes! Groups investigate the sum of the angles of a triangles with two method—measurements and transformations. Using diagrams of bicycles, classmates find the types of triangles formed by the seat and axles. They make conclusions on the engineering reasons of the locations of the largest and smallest angles.
- Conduct a quick review of angle relationships, such as supplementary and vertical
- Groups need protractors and patty paper
- Individuals should be able to solve linear equations
- Includes suggestions for accommodations
- Contains answer keys to help with grading
