The tangent plane on an ellipsoid is a surface that is parallel to the two dimensional sheet of paper. This means it doesn’t touch the ellipsoid at any point and always remains perpendicular to the major axis. The tangent plane can be found by drawing a straight line from any point on the surface of the ellipsoid, through its center, and then outwards along a line perpendicular to one of its axes until it reaches the two dimensional sheet of paper.

It’s important because many mathematical calculations are performed in this way – if you want to know what shape something occupies when they go through space for example. Additionally, different points within an object may have different potential energies due to their distance from other objects
