This resource focuses on essential concepts in 3D geometry, including how to calculate the distance between two points in three-dimensional space, find midpoints, and determine intercepts. It includes practice problems with clear examples, such as finding distances between points like (3, -2, 5) and (-1, 4, -2), as well as how to graph the equation of a plane. An ideal study guide for students preparing for midterm examinations, it also outlines key similarities to two-dimensional calculations while emphasizing the additional complexity of three dimensions.
