why-are-lines-180-degrees

Join us as we extend our understanding of circles to understand why the degree measure of any straight line is 180. This lesson features Jason Kidd and his famous "we're going to turn this team around 360 degrees" quote!

This lesson answers the questions: Why is a straight line 180 degrees? How many degrees are in a straight line? What is a linear pair? What are supplementary angles?

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.
