FACTS ABOUT TYPES OF QUADRILATERALS REVEALED

The main cuts down to Brahmagupta's components from the cyclic quadrilateral situation, given that then pq = ac + bd.Observe one: By far the most normal trapezoids and isosceles trapezoids would not have perpendicular diagonals, but there are infinite quantities of (non-identical) trapezoids and isosceles trapezoids that do have perpendicular diago
