A zero-dimensional shape is a point.
Yes.
It has length and width but no height
A closed 2 dimensional shape is a polygon
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.
It has length and width but no height
A closed 2 dimensional shape is a polygon
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.
A three-dimentional shape at all points equidistant from a straight line.
