A point is a location in space that has no size or dimension. It is often represented by a dot and can be described by its coordinates, which indicate its position along the x, y, and z axes.
A line is a straight path that extends infinitely in both directions. It is defined by two points and can be represented by a line segment with an arrow on each end to indicate its infinite nature.
The distance between a point and a line is the shortest distance between the two. It can be measured by drawing a perpendicular line from the point to the line and finding the length of that line.
Yes, a point can be on a line. In fact, a line is made up of an infinite number of points.
The distance between two points is calculated using the distance formula, which is the square root of the sum of the squares of the differences between the x, y, and z coordinates of the two points. It is often written as d = √[(x2 - x1)2 + (y2 - y1)2 + (z2 - z1)2].
