Final answer:
The tip of a needle, the edge of a knife, and the still surface of a lake are examples of a point, line, and plane respectively.
Step-by-step explanation:
A point is a location with no size or shape and is represented by a dot. The tip of a needle can be considered a point as it is a small location. A line is a straight path with no thickness that extends infinitely in both directions. The edge of a knife is an example of a line. A plane is a flat surface that extends infinitely in all directions. The still surface of a lake can be thought of as a plane.
