This PowerPoint presentation is designed to review perimeter as well as introduce the concept of finding the remaining side of a polygon by adding all of the known sides and subtracting that sum from the perimeter. In addition, the concept of a regular polygon is introduced. This presentation addresses perimeter from the perspective of adding all of the sides versus using formulas. The actual calculations to arrive at the answers are intentionally not shown so as to allow the teacher flexibility in presentation (ex. students and/or teacher can illustrate if a whiteboard device is used in the classroom) and pacing.
