We're having a hard time making out the dark grey area from here.
But the intersection of a plane and a sphere is always a circle.
The dark area is so dark that I'm unable to see it from here. But I do know that in general, the intersection of a plane and a sphere is a circle.
A circle, which could degenerate to a point.
plane shape
A two-dimensional cross-section of a sphere is represented by a circle. When a plane intersects a sphere, the intersection forms a circular shape, with the size of the circle varying depending on how the plane cuts through the sphere. If the plane passes through the center of the sphere, the resulting circle will have the largest diameter, while other intersections will produce smaller circles.
a circle!

plane shape
The shape described by the intersection of the cone and the plane is simply a circle.
a circle!
It has a curved surface.

If your question is " What is the shape of a sphere's tangent?" , then the answer is : a plane. A plane basically touches the sphere at only one point and hence , it should be a plane. It cannot be a straight line , as a straight line is a tangent for 2D objects,( ie.) a circle.
not quite a cirlcel but an oblong circle.
It is a horizontal cross-section. Its shape will depend on the shape of the solid and its orientation.
In geometry, the only shape that has one surface is a plane.
