Final answer:
The 'extension of a point' refers to the concept of extending a point along a line or in space.
Step-by-step explanation:
The 'extension of a point' refers to the concept of extending a point in a given direction. In mathematics, a point has no dimensions and can be thought of as a single precise location. When we talk about the extension of a point, we are considering the theoretical continuation of that point along a line or in space.
For example, if we have a point A and we extend it in a specific direction, we can imagine that the point continues infinitely along that line. Similarly, if we extend a point in three-dimensional space, we can imagine the point continuing indefinitely in that direction.
