c. the surface of a flat table. just took the test
Point
A triangle, but only if the line segments are straight.
A polygon is a 2-dimensional shape with 3 or more sidesa closed plane figure with three or more sides that are straight
The solid figure having eight vertices is the hexahedron. A cube, which has six faces (classifying it as a hexahedron) as well as the eight vertices, is a regular hexahedron. It is doubtless the best example of this category of geometric shapes. A link can be found below for more information, and some drawings to really help lock in the idea.
a cylinder is basically a solid bounded by a cylindrical surface and two parallel planes (the bases) or a surface generated by rotating a parallel line around a fixed line
What I think is that the perimeter is the distance around a figure. :)

That figure is best described as a "triangle".
Kinetic energy best describes the motion of the particles in a piece of steel.
Covalent Network
No. It best describes the outer core. The inner core is made up of solid iron.

all ofthe changes on earth surface occur slowly
A rectangle.
