Shapes that have only square corners, or right angles, include rectangles, squares, and certain types of polygons like right-angled trapezoids. These shapes are characterized by their 90-degree angles at each corner. In the case of polygons, all interior angles must be right angles for them to have square corners. Examples include a square, which has four equal sides and corners, and a rectangle, which has opposite sides equal and also features four right angles.

circle: no corner triangle: 3 corners rectangle and square:4 corners pentagon:5 corners
A point has no corners and no sides. There are several geometic shapes with no corners and only one side. Some of the shapes are circle, oval, and sphere.
square based pyramid
A parallelogram has 2 pairs of parallel sides, and provided that it isn't a square, it has no square corners. If necessary, you could call it an "oblique parallelogram" to indicate that it isn't square.
All of them apart from a circle
There is only the rectangle, with a square as a special case.

square based pyramid
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.
