# Interactive video lesson plan for: ☆ Practice with Geometry Proofs involving Isosceles Triangles | Common Core Geometry

#### Activity overview:

Join us on this flipped math lesson where we visually explore two geometry proofs involving isosceles triangles. For more MashUp Math content, visit http://www.mashupmath.com and join our free mailing list! :)

This lesson answers the questions: How do I prove that two triangles are congruent? How do I prove that a triangle is isosceles? What is the addition postulate? What is the subtraction postulate? What is CPCTC?

Our lessons are perfect for flipped classroom math teachers and students. This lesson is aligned with the common core learning standards for math and the SAT math curriculum as well.
