No shape, its impossible for a shape to have 0 sides because even a line has 1 side.
It can't exist, but if some stupid reality paradox happened in some 2D universe then I have some names.
a shape with equal sides
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.
The Shape That Has 8 Sides Is A Octagon Which Has 8 Equal Sides
It does not have any sides it's shape of an ovalAN OBLONG SHAPE IS NOT A OVAL
it begins with A
A point. Other shapes may not have straight sides but that does not mean that they do not have sides.
A shape cannot have only one side because it would not be closed. A shape must have at least three sides to be a closed figure (no "gaps")
It can have anywhere between 0 and 12 pairs of parallel sides.
The semi circle is a shape which has 1 line of symmetry 1straight side 0 equal length sides 0 parallel sides 2 vertices 0 diagnals
A shape with 7 sides.
a pentagon has 5 sides total, and no parallel sides. A hexagon has 6 sides, so it has 3 parallel sides. any shape with an odd number of equal sides has 0 parallel sides, no matter how many sides it has. every shape with an even number of equal sides will have the # of sides divided by 2 (#/2) of parallel sides.
