How to determine if two planes are coplanar, but have different origins

hello, is there a way to determine if two planes are coplanar, except just have different origins. I feel like this should be pretty simple but I cant just use the normal vector, because that only helps me determine if two planes are parallel. not coplanar. Please advise

Two options:

  1. Planes are coincident if they share a point and have identical normal vectors. It sounds like you are already aware of the normal vector check. You can take the origin point of Plane A and find the Geometry.ClosestPointTo Plane B. If closest point on B is the origin point of A, then coincident planes. If the closest point isn’t the origin point, parallel planes.

  2. Clockwork has a Coplanar check node:
