This Positive and Negative Angles and Arcs lesson plan also includes:
To better understand that the intersection point of two lines lies inside a circle, learners use their keen measurement skills. They discuss arcs, rays, tangent lines, and reflex angles. Then, they put their skills to work as they observe the relationship between the measure of the angle of intersection of two lines and the measure of the intercepted arcs. Critical thinking, problem solving, and mathematical applications make this a very nice lesson.
