Centroid : In mathematics and physics, the centroid or geometric center of a plane figure is the arithmetic mean position of all the points in the figure.
Sector : Sector is a geometric figure bounded by two radii and the included arc of a circle.
Segment : In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints
Parabola : A parabola is a curve where any point is at an equal distance from: a fixed point (the focus ), and. a fixed straight line (the directrix )
Orthocentre : The orthocenter is the point where all the three altitudes of the triangle cut or intersect each other.
