The Classification of Triangles
Lecture no. 15 from the course: Geometry: An Interactive Journey to Mastery
Taught by Professor James Tanton | 30 min | Categories: The Great Courses Plus Online Mathematics Courses
Continue the work of classification with triangles. Find out what mathematicians mean when they use words like scalene, isosceles, equilateral, acute, right, and obtuse. Then, learn how to use the Pythagorean theorem to determine the type of triangle (even if you don’t know the measurements of the angles).
