Question

I have four sides, four Hexagon
right angles.

Answer 1

Talking about closed figure, on flat plane squares and rectangles are such figures with least number of sides. Polygons with any no. of sides ≥ 4 can have 4 right angles.

On curved planes also such figures exist, a grid made by two meridians and two latitudes on a globe is the most popular example.

Similarly there can be such figures on all kinds of planes including ellipsoids, paraboloids and hyperboloids.
