This document discusses three-dimensional coordinate systems and geometry. It defines a polyhedron as a 3D shape formed by four or more intersecting polygons and notes that three coordinates are needed to locate a point in three-dimensional space using an x, y, z coordinate system where the axes are perpendicular. As an example, it gives the point located at (3, 2, 4) in such a coordinate system.

Formulas in 3 d
- 2. • A polyhedron is formed by four or more polygons that intersect only at their edges.
- 5. • Space is the set of all points in three dimensions. • Three coordinates are needed to locate a point in space. • A three-dimensional coordinate system has 3 perpendicular axes: the x-axis, the y-axis, and the z-axis. • An ordered triple (x, y, z) is used to locate a point.
- 6. • Example: Locate the point (3, 2, 4)
- 7. z y x
