square circle
Contradictory shape combination
A square circle is a geometric impossibility—a shape that is simultaneously a square and a circle, which contradicts their definitions.
Philosophers use it as the paradigm case of a logical contradiction, something that cannot exist even in principle: Not even God could create a square circle.
It tests the limits of omnipotence and possibility.
