No shape, its impossible for a shape to have 0 sides because even a line has 1 side.
a line
a circle
A 0-sided shape is called a circle. Yes, I know it sounds like a trick question, but a circle technically has 0 sides because it's defined by its curved boundary. So, there you have it, a shape with no sides but still manages to be round and fabulous.
A crescent has two [curved] sides and two corners.
a shape with equal sides
It does not have any sides it's shape of an ovalAN OBLONG SHAPE IS NOT A OVAL

rhombus
A 0-sided shape is called a circle. Yes, I know it sounds like a trick question, but a circle technically has 0 sides because it's defined by its curved boundary. So, there you have it, a shape with no sides but still manages to be round and fabulous.
trapizoid
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
