pyramid (not including the vertex) Prism
A pyramid could be constructed from 4 or more triangles.
It depends on the shape. The number of edges, alone, is not enough to determine a unique shape.
A straight line.A straight line.A straight line.A straight line.
Any triangular structure. The triangle is used in building structures like towers and bridges because the three sides of a triangle, when locked together at their ends, are very strong and do not change shape. It's one of the most important shape in constructions. The circle is another important shape too.
A bad conductor in the shape of a disc is preferred in Lee's disc method for thermal conductivity measurements because the disc shape ensures uniform heat flow in all directions, simplifying calculations. Additionally, the disc shape allows for easy measurement of the temperature difference across its diameter, which is crucial for determining thermal conductivity accurately.
More complicated polygons.
a cone (not including the vertex) and a cylinder

Disc shaped.

A pyramid could be constructed from 4 or more triangles.
Most bacterial have the same shape, and there are millions of different species of bacteria. Try and differentiate a bag of marbles by shape alone.
biconcave (A.N)
Yes, a solid will retain its shape even if left alone because the particles are tightly packed and have minimal movement. This allows solids to maintain their fixed shape and volume.
actually not all are constructed in v shape,, sometimes its u shape, somtimes its semi circular, usually v canals are used for ditch canals, or as temporary ditch. it is a dug up soil formed in v shape in order to create a canal for storm water. it was formed v on order to avoid the soil at sides of canal to erode
Pyramids are constructed from triangular shapes and can have square or triangle bases
