Yes.
A semicircle.
The 2D equivalent of a sphere is a circle so it follows that the 2D equivalent of a hemisphere is a semicircle.
The 2D shape of a hemisphere is a semicircle. When you take a hemisphere, which is half of a sphere, and project it onto a flat surface, it creates a semicircle, representing the curved surface. The flat side of the hemisphere corresponds to a straight line, completing the shape. Thus, the 2D representation of a hemisphere is a semicircle plus a diameter.
The answer might depend on what the first nine are. Is a circle already counted? A semicircle, a quadrant, an ellipse, and so on. And if not, why not?
A semicircle is a two-dimensional shape that is half of a circle, with a flat edge as the diameter. A hemisphere, on the other hand, is a three-dimensional shape that is half of a sphere, with a curved surface. Essentially, a semicircle lies in a plane, while a hemisphere is a solid object.

A rhombus is a 2D shape.
A 'Quadrilateral' is a 2-dimensional, 4 sided polygon. The following names are quadriltaerals;- square, rectangle, rhombus, trapezium, parallelogram, kite, and an irrelgular qudarilateral. NB In 3-dimensional space, ther equivlanet is a 'CUBOID'.
this is the shape of 2d cone
