Z-Coordinate
The z-coordinate refers to the vertical position of a point in a three-dimensional coordinate system
The z-coordinate refers to the vertical position of a point in a three-dimensional coordinate system. It is one of the three coordinates used to locate points in three-dimensional space, along with the x-coordinate (horizontal position) and the y-coordinate (vertical position).
In a typical Cartesian coordinate system, the z-axis is perpendicular to the x-axis and the y-axis. When determining the z-coordinate of a point, you measure the distance along the z-axis from the reference point (usually the origin) to the point. If the z-coordinate is positive, the point is located above the reference point, and if it is negative, the point is located below the reference point.
For example, if we have a point P with coordinates (3, 2, -1), the x-coordinate is 3, the y-coordinate is 2, and the z-coordinate is -1. This means that the point P is located 3 units to the right, 2 units upward, and 1 unit below the reference point.
The z-coordinate is crucial in three-dimensional geometry, as it allows us to accurately position points, lines, and shapes in three-dimensional space. It is extensively used in various fields such as physics, engineering, computer graphics, and 3D modeling.
