  3. Sum of the interior angles is: S = (n -2) 180 S = (5 – 2) 180 or S = 3(180) Sum of the exterior angles is 360 , but we can view that as 2(180) So… total sum of interior and exterior angles (T) is: T = 3(180) + 2(180) or T = (3+2)180 T = 180(5)

  4. T = 180n – 360 is the total interior angle measure. The 360 can be thought of as 180(2). T = 180n – 180(2) Using the Distributive Property, we can now see that we have the formula developed in lesson 2.2, which is T = (n-2)180

  5. 3(180) 360 3(180) – 360 = 180 Total – exterior = interior

  6. x + 2x + 3x = 180 6x = 180 x = 30, 2x = 60, 3x = 90 Supplements: x + 2x + x – 20 = 180 4x - 20 = 180 4x = 200 x = 50, 2x = 100, x – 20 = 30 Supplements:

  7. Partner Quiz Expectations • Make corrections on each paper • Quiz problems were chosen randomly throughout your group’s papers • At least one of every problem was corrected • If your group had all of the same work and answers, you only have to check problems that are marked wrong • No calculators • Watch your time and use it well • Staplepapers together and place in turn-in box • When you finish, work on your math Homework.
