Point
A point marks an exact position. It has no length, width or thickness. In coordinates it is written (x, y) or (x, y, z).
Point📐 Formula
Distance from the origin: OP = √(x² + y² + z²)
✏️ Worked example
P(3, 4, 0): OP = √(9 + 16 + 0) = √25 = 5 units.
🌍 Where it is used
GPS positions, pixels on a screen and map pins are points.
