In this lesson, we will review the key concepts of complementary angles, which sum up to 90 degrees. You will work on various angle constructions, including determining the complement of angle BOC, which is angle COD. For homework, you will solve for angle NMO, where angle LMO equates to expressions involving x. Complete four constructions during the period to secure full credit, and earn tickets for each completed task. The first three students to finish all constructions will receive a small prize.

Lesson 1.10AIM: Review of Constructions DO NOW: Complementary Angles add up to 90 degrees. An angle complementary to BOC is COD.
Homework Review Angle NMO = Angle LMO 6x + 19 = 9x - 14 -6x -6x 19 = 3x - 14 +14 +14 33 = 3x 11 = x
Review Directions • You must complete four constructions by the end of the period for full credit. • You will receive one ticket for each construction you complete. • The first THREE people who complete all four constructions will win a small prize.
