- 2. In geometry, a hexagon is a six-sided polygon or 6-gon. The total of the internal angles of any simple hexagon is 720°.
- 3. plane A coordinate plane is a two-dimensional plane formed by the
- 7. Line In elementary mathematics, a number line is a picture of a graduated straight line that serves as an abstraction for real numbers, denoted by \mathbb {R}. Every point of a number line is assumed to correspond to a real number and every real number to a point.
- 8. In mathematics, the origin of a Euclidean space is a special point, usually denoted by the letter O, used as a fixed point of reference for the geometry of the surrounding space.
- 10. A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.
Down
- 1. the secondary or vertical axis of a system of coordinates points along which has a value of zero for all other coordinates
- 4. In geometry, an octagon is an eight-sided polygon or 8-gon
- 5. In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.
- 6. A ruler sometimes called a rule or line gauge is a device used in geometry and technical drawing and the engineering and construction industries to measure distances or draw straight lines.
- 9. In mathematics, the graph of a function f is the set of ordered pairs, where f(x) = y. In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane
