they both have sides and corners. they both have sides and corners.

Quadrilateral.

It is very possible considering non-closed shapes. For example, picture the letter "M" but drawn into the third dimension, sort of like a open roof gutter (which has 2 corners and 3 sides). It will have 3 corners and 4 sides (an "L" would have 1 corner and 2 sides).

Yes

square

A triangle is the only polygon with 3 corners (vertices). There is no polyhedron with 3 corners.

It is a square as square has 4 sides and all of them are equal. Also it has 4 corners.

I guess shapes that have few sides have sharper angles for instance a triangle has very sharp corners whereas a henagon has corners but they are very rounded.

The shapes that I can think of are a square, rectangle, rhombus and a diamond
