# Intersect Line Line¶

## Description¶

This node takes two lines and returns the locations of two points (one on each of them) that are closest to each other. If the lines intersect, that is, they are not skew, then the two points will be equal to the point of intersection.

## Illustration¶

Blue points are the input points and orange points are the output points. Orange points are the closest points on the lines.

## Inputs¶

**Line 1 Start**- The location of the starting point of the first line.**Line 1 End**- The location of the ending point of the first line.**Line 2 Start**- The location of the starting point of the second line.**Line 2 End**- The location of the ending point of the second line.

## Outputs¶

**Closest On Line 1**- The location of the closest point on line 1.**Closest On Line 2**- The location of the closest point on line 2.**Is Valid**- A boolean which is True if a closest pair was found and False if not. Closest pair won’t be found only if both lines were parallel.
