This product was extremely helpful for my ELLs especially. Obviously, it does not include all the angles relationships created when a Parallel Line is cut by a Transversal but is a great resource to hang in your classroom, include in a powerpoint or laminate and hand to your students. Two options are included: 11 x 8.5 (landscape) and 4 to a page 11 x 8.5 (landscape) for easy and versatile use.
