The two straight lines which intersect each other at a point in a plane are defined intersecting lines.

Straight lines are actually intersected at a point in the plane due to their non-parallelism. In other words, if two straight lines do not maintain equidistance at all their opposite points, they are non-parallel lines and surely get intersected at a point in the plane. Therefore, the two straight lines are known as intersecting lines geometrically.

There are two possibilities for the lines to get intersected at a point in the plane. One case is, straight lines are intersected at a point in the plane directly. The second case is, the straight lines have a chance to get intersected at a point in the plane.

1.

Intersecting Lines

$\overleftrightarrow{MN}$ and $\overleftrightarrow{OP}$ are two straight lines. These two straight lines do not maintain equidistance separation in the plane and they intersected at a point $I$. Now, the straight lines $\overleftrightarrow{MN}$ and $\overleftrightarrow{OP}$ are called as intersecting lines geometrically.

2.

Possibility of Intersection of Lines

$\overleftrightarrow{JK}$ and $\overleftrightarrow{LM}$ are two other straight lines and they do not maintain equal distance between them. It seems they do not intersect each other but they surely intersect at a point at somewhere in the plane if they are extended. Let us say the chance of intersection is at point $I$ in the plane.
