    This resource is an excellent tool for tenth graders when introduced with transversals, obtuse angles, acute angles, and when tenth graders are doing proofs. Furthermore, teachers can have a field day with this applet when teaching this topic, and looking for ways to explain the definitions of certain mathematics terms.
