Brahmagupta quadrilaterals - K. R. S. Sastry The Indian mathematician Brahmagupta made valuable contributions to mathematics and astronomy. He used Pythagorean triangles to construct general Heron triangles and cyclic quadrilaterals having integer sides, diagonals, and area, i.e., Brahmagupta quadrilaterals. In this paper we describe a new numerical construction to generate an infinte family of Brahmagupta quadrilaterals from a Heron triangle. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
