# Concurrent Lines

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.

## Example

Concurrent Lines

$\stackrel{↔}{RS}$

,

$\stackrel{↔}{TU}$

,

$\stackrel{↔}{VW}$

and

$\stackrel{↔}{XY}$

are four straight lines. All are in same plane. Assume, they pass through a point in the plane. Now, the straight lines

$\stackrel{↔}{RS}$

,

$\stackrel{↔}{TU}$

,

$\stackrel{↔}{VW}$

and

$\stackrel{↔}{XY}$

are called concurrent lines.
