This math topic focuses on applying the Pythagorean Theorem in three-dimensional contexts, specifically examining scenarios involving double triangles where students calculate lengths from known hypotenuse measurements. There are several questions where students are given the distance between two points in 3D space and they must determine the length of one of the side dimensions. Each question provides multiple-choice answers. This subject serves as part of an introduction to the broader concept of the Pythagorean Theorem in 3D geometric contexts.
