A circle as it has infinite number of sides
the shape with the most sides is unknown
Such a shape cannot exist because it is always possible to increase the number of sides by 1 by simply cutting off one vertex.
A shape with three and only three sides is a triangle, but it is not possible for a triangle to have three perpendicular sides.
A 3d shape can have infinite sides
It is not possible to have five perpendicular sides; four or eight, but not five. A shape with five equal sides is a pentagon.
There is no limit to the number of sides that a shape can have. It is not possible to tell what the largest number is unless you know all the shapes that exist in the universe.
There is no such thing as the shape with the 'most' sides. No matter how many sides you draw a shape with, somebody else can easily come along and draw a shape with one or two or fifty more sides. The more sides a shape has, the more it gets to look like a circle.
I do not believe that such a shape is possible. At least, not without going into exotic geometries.
Its not possible to have less than 4 four side that the most idiotic question i ever heard, No Sides, No Angles.
no because that is not possible
a regular shape which includes many sides possible but all sides are equeal in length
octagon
