About the Lesson

Watch the activity tutorial

Students are provided with an activity file that includes an interactive diagram of a three dimensional box. Each side (edge) of the box can be varied with the subsequent diagonal length displayed. Students compute the length of the diagonal to verify Pythagoras’s theorem in three dimensions.
