Full course description
Welcome to Tangent SegmentsTheorem Lesson!
Representations of a problem-based lesson that leads to the Tangent Segments Theorem which states that if a circle is tangent to two intersecting lines, the points of tangency are equidistant from the point of intersection of the lines. By working on the problem of finding a circle tangent to two intersecting lines, students are led to see that the points of tangency must be equidistant from the intersection of the lines. In this lesson library, you will find diverse representations of this lesson in the form of animations and engaging storyboards with cartoon characters prepared by teachers from around the world. You will also have the opportunity to reflect on these lesson representations by adding annotations, reviewing annotations contributed by other teachers, and starting a discussion thread.
