A fixed point from which a figure is turned.

The fixed point from which a figure is turned is called the center of rotation.

The transformation that involves the circular turning of a figure around a fixed central point is called a rotation.

A two-dimensional graph created when a horizontal number line intersects with a vertical number line is called a coordinate plane or a Cartesian plane.

Two or more lines that move in the same direction and never intersect are called parallel lines.
