Intersecting Lines

Two lines that cross each other at a particular point are called intersecting lines. The point where two lines cross is called the point of intersection. 


Definition of Intersecting Lines:

If two lines have one common point, they are called intersecting lines.

For Example:

(i) Two adjacent edges of a notebook

(ii) Crossing roads

(iii) The multiplication sign (×) etc. are the examples of the intersecting lines.

In the given figure \(\underset{AB}{\leftrightarrow}\) and \(\underset{CD}{\leftrightarrow}\) intersect each other at point O.

Intersecting Lines

Working Rules to Draw Intersecting Lines:

Step I: Draw a line \(\overleftrightarrow{AB}\) and another line \(\overleftrightarrow{CD}\).

Step II: Let them intersect each other at a point O.

Step III: The point of intersection O lies on line AB as well as on line CD.

Now, we can say that lines AB and CD are intersecting lines. They intersect at one point O.
