Instructional Ideas

• Have pupils research real-life uses of special right triangles 

Classroom Considerations

• Learners need to be proficient with the Pythagorean Theorem, including using variables as lengths
• Lesson can be split over the course of two days by investigating each special right triangle separately

Pros

• Pupils investigate relationships rather than being told what they are
• Teacher resource includes suggested questions to use to guide class discussions

Cons

• Includes very few examples and practice problems
