Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Bearing
Bearing is a way of describing direction in navigation and geometry, typically measured in degrees from the north direction. It is expressed as an angle, with 0° representing north, 90° east, 180° south, and 270° west. Understanding bearings is crucial for accurately interpreting and matching them with corresponding graphical representations.
Quadrants
The Cartesian plane is divided into four quadrants, each representing a specific range of angles. Quadrant I contains angles from 0° to 90°, Quadrant II from 90° to 180°, Quadrant III from 180° to 270°, and Quadrant IV from 270° to 360°. Recognizing which quadrant a bearing falls into helps in visualizing its corresponding graph.

Quadratic Formula
Graphical Representation of Angles
Graphical representations of angles, such as those found in polar coordinates or unit circles, illustrate how angles correspond to specific directions. Each angle can be plotted on a graph, allowing for visual interpretation of bearings. Understanding how to read and interpret these graphs is essential for matching bearings with their correct visual representations.
