Coordinate plane
Coordinate plane A coordinate plane (Cartesian plane) is a plane formed by a horizontal line (an axis) and a vertical line (another axis) that intersect at a point called the origin. A plane containing two perpendicular axis (x and y) intersecting at a point called the origin (0,0).A point position is denoted using pairs of coordinates (x; y) , e.g. A(3, 1). The […]
Cylinder
Cylinder A cylinder is a 3D solid shape that consists of two identical and parallel bases linked by a curved surface.
