Students work with a partner. One partner does the problems on the left side, the other partner does the questions on the right side. The questions are different, however, the answers are the same. One both students arrive at the same answer they can move on to the next question.

This Smartboard Lesson includes
• a Do Now that reviews setting up proportions since they will be used in working with the Side Splitter Theorem and the Angle Bisector Theorem
• a slide to recall several equivalent forms for given proportions. These proportions will be used in later slides.
• a s
