Van Schooten's theorem is a result in geometry that deals with the properties of cyclic quadrilaterals. It states that for any cyclic quadrilateral (a four-sided figure whose vertices all lie on a single circle), the lengths of the segments connecting the midpoints of opposite sides are equal to half the lengths of the diagonals of the quadrilateral.
