Triangle Classification

This Triangle Classification lesson plan also includes:

Oh triangle, where are the points that will make your type? Given a line segment, pairs determine the location of a third point to create the six different types of triangles. The teacher provides a jumping off point by leading a discussion on creating right triangles. With the online activity, pupils trace a locus of points that create specific types of triangles.
