2. Two lines in a plane always intersect each other.
3. A line extends indefinitely in both the directions.

4. The point of intersection of two lines is called the point of concurrence.
5. Only one line can be drawn through a given point in a plane.
6. Two lines are called parallel if they do not intersect each other.

7. Three or more points which lie on the same line are called collinear points
