Product Description
What do Papa Bear, Mama Bear and Baby Bear have to do with triangles? This is how I teach the 3 similar triangles that exist when an altitude is drawn in a right triangle. It produces three similar triangles. A big one, a medium one and a small one. This geometry lesson covers the Right Triangle Altitude Theorem and its corollaries. First, students practice drawing the three similar triangles and setting up proportions. The second part of the lesson covers geometric mean and how it is used in corollary 1 and corollary 2 to find missing sides. This resource contains notes, practice, a challenge problem, a lesson plan and practice of Pythagorean Theorem.
