BASIC GEOMETRY TERMSBasic geometry terms explained
A line is a collection of points which extends forever.The arrow(s) indicates that the line extends forever in the marked direction.
If a line extends infinitely only to one side, it is termed as a ray.
If we join two rays, and with a common endpoint, it is called as an angle.
