More than two straight lines which pass through a point in a plane are defined concurrent lines.

Straight lines are often appeared by passing through a point in a plane. Two lines are passed through a point in most of the cases and they are known as intersecting lines but more than two straight lines are also passed through a point in some special cases and they are called concurrent lines.

It seems, straight lines pass through a point but they are intersected each other at that point.

Concurrent Lines

$\overleftrightarrow{RS}$, $\overleftrightarrow{TU}$, $\overleftrightarrow{VW}$ and $\overleftrightarrow{XY}$ are four straight lines. All are in same plane. Assume, they pass through a point in the plane. Now, the straight lines $\overleftrightarrow{RS}$, $\overleftrightarrow{TU}$, $\overleftrightarrow{VW}$ and $\overleftrightarrow{XY}$ are called concurrent lines.
