Common Core Math - Grade 7
Lesson Plan
Use facts about supplementary, complementary, vertical, and adjacent angles to solve simple equations
Goals / Objectives
Define supplementary, complementary, vertical, and adjacent angles
State the angle measure relationships for each pair type (supplementary: sum = 180 degrees; complementary: sum = 90 degrees; vertical angles: equal)
Write an equation to represent an angle relationship given a figure with an unknown angle
Solve the equation to find the unknown angle measure
Verify the solution by checking that the angle relationship holds
Apply multiple angle relationships in the same figure to solve multi-step problems
