Yes.
A closed 2 dimensional shape is a polygon
It has length and width but no height
A two dimentional shape with 1 side and 1 vertex.
Not possible ! A rectangle is a two-dimentional shape. Volume is a measure of capacity.
Yes.

If it is a 2 dimentional shape it is called an 'octadecagon'
There are quite a few. Circles, squares, triangles...
a planet
A shape that it is 3D and has sides, corners and faces
A two dimentional shape with 1 side and 1 vertex.
An enneadecagon (or enneakaidecagon or nonadecagon).
A 3-D circle is a "sphere" (a ball shape).
No, a particle in one dimension with zero speed will have zero velocity. Velocity is a vector quantity that includes both the speed and direction of motion, so if the speed is zero, the velocity will also be zero since there is no direction of motion.
Hello, a 4-d shape is a shape that nobody knows, i do though a four D shape is a four dimentional object which you can pick up. it is a tesseract. (ffaarrtt)
