Parallel Lines and Transversals in the Real World

This is one lesson in a larger Unit Plan that covers many properties of triangles and several other theorems.  It has proofs, real world problems, constructions, a unit project, assessments, and more.  In Lesson 5, “Is This Assignment on the Level?”, students produce a drawing illustrating the relationships of angles formed by transversals.  Includes a grading rubric.  The entire unit plan can be found here. This is a portion of a Unit Project, however, it could be used as a stand alone assignment as well. The "launch" is also an interactive review of vocabulary.
