I believe the fewest number of sides in a planar, non-convex polygon is four.
In two dimensions, a circle, ellipse. In fact any smooth closed curve.
The shape with the fewest corners, ie the sphere.

A quadrilateral always has 4 sides... no more no less.

the fewest sides of the same length a quadrilateral can have is 2. it can be in whatever shape as long as the each pair or lines has the same equal length. * * * * * Wrong! The correct answer is 0. All four sides of a quadrilateral can have different lengths. Such a quadrilateral has no specific name to distinguish it from other plane figures with four straight sides.
Spheres, eggs, footballs, oblate and prolate spheroids, as well as most other finite solids of revolution, each have only two sides ... the in-side and the out-side.
The shape with the fewest corners, ie the sphere.

A triangle has the fewest amount of sides possible to create a closed figure.
A shape with 7 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.
a shape with equal sides
a shape with ten sides
