The Pythagorean Theorem
Lecture no. 5 from the course: Geometry: An Interactive Journey to Mastery
Taught by Professor James Tanton | 28 min | Categories: The Great Courses Plus Online Mathematics Courses
We commonly define the Pythagorean theorem using the formula a2 + b2 = c2. But Pythagoras himself would have been confused by that. Explore how this famous theorem can be explained using common geometric shapes (no fancy algebra required), and how it’s a critical foundation for the rest of geometry.
