Our Angles and Equations lesson plan explores different ways angles can be used in equations to find missing angle measurements. The lesson focuses specifically on adding and subtracting angles. Students are asked to identify given shapes and angles and find the value of “x”, where “x” is an unknown angle. Students are also asked to write equations and solve them to find missing angles in order to demonstrate their understanding of the lesson.
At the end of this lesson, students will be able to use addition and subtraction to find the measure of an unknown angle.
