Investigations with Right Triangles to Deepen Students' Conceptual Understanding

Rich, open-middle tasks offer opportunities for students to explore concepts with depth. We explore a series of investigations with right triangles designed to improve students' conceptual understanding of geometry and proof. Ideas for how technology can enhance these tasks are offered along with multiple solution paths and student work samples.
