Rectangular coordinate system

 Rectangular coordinate system | Two-dimensional rectangular

Two or three lines drawn perpendicular to each other are called coordinate axes.

The system of coordinate axes is called a rectangular coordinate system or Cartesian coordinate system.

In rectangular coordinates, the horizontal line is called X axis.

In a rectangular coordinate system the vertical line is called the Y axis.

Two-dimensional rectangular coordinate system.

If two lines drawn perpendicular to each other are called a two-dimensional rectangular coordinate system.

Two-dimensional systems form plane.

Direction of a vector in a two-dimensional system is determined from the positive X axis in an anticlockwise direction.

In a two-dimensional system only one angel requires two directions.

Three Dimensional coordinate system.

If three lines are drawn perpendicular to each other then it forms a 3 dimensional rectangular coordinate system.

Three Dimensional systems form a space.

Three angles are required for direction of a vector in a three-dimensional system.

Head to tail rule.

Take any vector as a fast vector without changing the direction and the second vector drawn such as head of fast and tail of second must be joined without changing the direction.The resultant vector from tail of first toward head of last vector is called head to tail rule.
