Solving for Unknown Angles Using Equations (Continued...)

EngageNY 45 min(s)

Students solve for unknown angles in word problems and in diagrams involving all learned angle facts. Two lines meet at a point that is also a vertex of an angle. In the following examples and exercises, students set up and solve an equation for the unknown angle based on the relevant angle relationships in the diagram. Encourage students to note the appropriate angle fact abbreviation for any step that depends on an angle relationship.
