Answer: 1) point 2) line 3) plane.
Step-by-step explanation:
There are three undefined terms in geometry:
1) point 2) line 3) plane.
A point has only one dimension. A line is defined as something that extends infinitely in either direction but has no width . It is one dimensional . On the other hand a plane extends infinitely in two dimensions.
By using these 3 undefined terms the other geometric terms are defined.
