The Plane Angle is defined initially in 7-6/10-6, elbow,turned Shoulder, etc. and is in reference to the angle between the horizontal surface (the ground and it assumed to be flat).
This Plane Angle is applied to a line that is on the surface, the Plane Line 7-5/10-5. It is defined as the base line of the Plane.
The Inclined Plane Line is parallel to the Sweet Spot Plane Line (which is often considered to be the Target Line or Line of Flight Line and is defined as the Impact Line 2-N-0 which definite lies on the Sweet Spot Plane at all times)
Of the two primary Planes in TGM, the Inclined Plane is the plane the clubshaft travels on and the Sweet Spot Plane is what the Hands monitor the Feel, the drag/lag, motion, etc. (This may be refuted by others). I posted a thread in the lab about the Inclined Plane.
