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.
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.
plane shape
a circle!
It has a curved surface.
A circle, which could degenerate to a point.

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.
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.
In geometry, the only shape that has one surface is a plane.
a polyhedron * * * * * That is only if it is bounded by plane faces. A sphere, for example, is a three dimensional shape but is not a polyhedron: it is a solid shape.
A sphere sliced by a plane, eg a hemisphere.
A sphere, a cone, a section of a sphere or ellipsoid, a torus (doughnut) sliced by a plane perpendicular to its axis, a paraboloid. These are some examples.
Since a sphere is round it is a shape without a face.
