[b]Practice Converting Between Heading, Direction Angle, and Quadrant Bearing[/b] Enter a value for either Heading or Direction Angle and see how the vector and the other angle forms change. [list] [*][color=#0a971e]Heading (course, or bearing) are COMPASS angles and are measured CLOCKWISE from NORTH.[/color] [*][color=#c51414]Quadrant bearing is a short-cut notation for heading and is measured FROM the first letter (either NORTH or SOUTH) TOWARD the last letter (either WEST or EAST).[/color] [*][color=#1551b5]Direction angle (our vector angle) is the TRIG angle measured COUNTERCLOCKWISE from the positive X-AXIS.[/color] [/list]
