# skspatial.objects.Plane.intersect_plane¶

Plane.intersect_plane(other: Plane, **kwargs) Line[source]

Intersect the plane with another.

The planes must not be parallel.

Parameters
otherPlane

Other plane.

kwargsdict, optional

Additional keywords passed to `Vector.is_parallel()`.

Returns
Line

The line of intersection.

Raises
ValueError

If the planes are parallel.

Examples

```>>> from skspatial.objects import Plane
```
```>>> plane_a = Plane([0, 0, 0], [0, 0, 1])
>>> plane_b = Plane([0, 0, 0], [1, 0, 0])
```
```>>> plane_a.intersect_plane(plane_b)
Line(point=Point([0., 0., 0.]), direction=Vector([0, 1, 0]))
```
```>>> plane_b = Plane([5, 16, -94], [1, 0, 0])
>>> plane_a.intersect_plane(plane_b)
Line(point=Point([5., 0., 0.]), direction=Vector([0, 1, 0]))
```
```>>> plane_b = Plane([0, 0, 1], [1, 0, 1])
