If two lines touch each other in such a way that there is a point in common then these lines are called intersecting lines.
That common point is called a Point of Intersection.
Here, line l and m intersect each other at point C.
If a line intersects two or more lines at different points then that line is called Transversal Line.
When a transversal intersects two lines then they make 8 angles.
Some of the angles made by transversal-
|Types of Angles||Angles shown in figure|
|Interior Angles||∠6, ∠5, ∠4, ∠3|
|Pairs of Corresponding Angles||∠1 and ∠5,∠2 and ∠6, ∠3 and ∠7,∠4 and ∠8|
|Pairs of Alternate Interior Angles||∠3 and ∠6,∠4 and ∠5|
|Pairs of Alternate Exterior Angles||∠1 and ∠8,∠2 and ∠7|
|Pairs of Interior Angles on the same side of the transversal||∠3 and ∠5,∠4 and ∠6|
