7. Introduction to Three-Dimensional Geometry
The chapter explores three-dimensional geometry, extending the concepts of coordinate geometry into space. It details the coordinate axes, the coordinates of points in three-dimensional space, and important formulas for calculating distances and intersections within this space. This foundational knowledge is crucial for analyzing spatial relationships and understanding geometric figures that exist beyond the two-dimensional plane.

Key Concepts
- -- ThreeDimensional Geometry
- A field of study that analyzes figures and spatial relationships in three dimensions using coordinates.
- -- Coordinates
- A triplet of values (x, y, z) that define a point's position in three-dimensional space.
- -- Distance Formula
- The formula used to calculate the distance between two points in space, derived from an extension of the Pythagorean theorem.
- -- Section Formula
- A formula that determines the coordinates of a point that divides a line segment between two points in a given ratio in three-dimensional space.
