    Don't the internal angles need to be 90°? Two of those right angles aren't right angles on the inside.

      Lines that intersect a circle like that aren't "right angles" tho, they're called "normal" to the circle - in other words pointing directly toward the center. A normal line is at right angles to a tangent line, but not to a curve.

        Imagine you have a cookie cutter in that shape. Cut a cookie as thick as the chord of the largest arc.

        View the new vertical surface of the longest arc that is now a cylindrical section.

        Viola, square. 😁
