The challenge for this Figure This! activity, reviewed for grades 6-8 by Illuminations, is to determine what amount of yourself you see when you look in a mirror, and if this amount changes as you back away from the mirror. Different geometrical concepts, such as, angles, reflections, lines of sight, and triangles, are used to figure out the answers. The purpose of this activity is to show the importance of recognizing how these concepts are related, and how they can be used in everyday professions. There are several suggestions of how to go about solving this challenge in the "Getting Started" section. For example, measure the height of the mirror and the height of yourself that you see in the mirror and compare them. There are also related questions in the "Try These" and "Think About This" sections along with interesting facts and background information in the "Did You Know" section. Less
