Detailed explanation-1: -Brahmagupta (ad 628) was the first mathematician to provide the formula for the area of a cyclic quadrilateral. His contributions to geometry are significant. He is the first person to discuss the method of finding a cyclic quadrilateral with rational sides.
Detailed explanation-2: -"Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628, ‘’ said Gobets. He developed a symbol for zero: a dot underneath numbers.
Detailed explanation-3: -In geometry, Brahmagupta’s theorem states that if a cyclic quadrilateral is orthodiagonal (that is, has perpendicular diagonals), then the perpendicular to a side from the point of intersection of the diagonals always bisects the opposite side. It is named after the Indian mathematician Brahmagupta (598-668).
