The center is the origin, with zero radii. In the same way, the angle is 180В° and 270В° for the left x-axis and bottom y-axis. We start measuring the angle from this line, and the angle is 0В° for all points on the right x-axis. In the below figure, the reference line is the right x-axis. Whenever we measure an angle, we use a reference line from which the angle is measured. AnticlockwiseДЄnticlockwise, as the name says, the angle is measured anticlockwise, opposite to the way in which the hands of a clock move. In the cartesian coordinate system, we define the position of a point by x and y, which are perpendicular distances from both axes, while in the polar coordinates, a point is identified by r and Оё.Д«ased on the direction of the measurement of the angle, we categorize polar graphs as anticlockwise and clockwise.

Theta (Оё), or better known as an angle, defines the angular position of a point from the reference line. It is a non-directional parameter it means it does not have direction. Radius (r) is the distance between the origin and a point on a polar graph. The polar coordinate system consists of two parameters: radius and theta.

Like the cartesian system, the polar coordinate has two variables (radius and theta) to uniquely define a point. Polar graphs are a two-dimensional coordinate system commonly used in navigation and studying a quantity by directions.
