Angles measured in the clockwise direction from the positive x-axis

In the Cartesian plane, angles can be measured in both positive (counterclockwise) and negative (clockwise) directions from the positive x-axis

Depends on whether the rotation is counterclockwise (positive) or clockwise (negative) from the positive x-axis

Positive angles measured in degrees or radians counterclockwise and negative angles measured in degrees or radians clockwise

Provides a framework for representing points, lines, and angles in a plane using x and y coordinates

By adding or subtracting multiples of 360° (or 2π radians), maintaining the same terminal side but changing the direction of rotation

Represented as positive or negative angles depending on the direction of rotation
