Coordinates of the Intersection of Two Lines
Calculates the coordinates of the intersection of two lines and the angle between them.
| Intersection coordinates xp | ,yp |
| Crossing angle θ |
The intersection angle is defined as the angle between the intersecting acute angles.
If two lines are parallel and have no point of intersection, the coordinates of the point of intersection are displayed as ±∞.
If two lines are parallel and have no point of intersection, the coordinates of the point of intersection are displayed as ±∞.
