Identifying Right Triangles and Theorems

This video tutorial, led by a special education virtual content specialist, covers an 8th-grade lesson on the Pythagorean theorem and irrational numbers. The lesson includes guidance on instructional strategies, technology use, and engaging students with disabilities and multilingual learners. Students explore triangle side lengths through group activities and discussions, focusing on identifying right triangles and understanding the properties of triangle sides. Additional resources for practice are provided, including IXL, Khan Academy, and Engage New York.
