검증된 단계별 안내

Step 1: Understand what a bearing is. A bearing is a direction measured clockwise from the north line. It is usually expressed in degrees from 0° to 360°, where 0° or 360° represents north, 90° east, 180° south, and 270° west.

Step 2: Identify the bearing given in the problem, such as 270°, and recall that this corresponds to a direction exactly west.

Step 3: For each bearing in Column I, visualize or sketch the direction starting from the north and rotating clockwise by the given degree measure.

Step 4: Examine each graph in Column II and determine which one matches the direction indicated by the bearing. For example, a bearing of 270° should point directly to the left (west) on the graph.

Step 5: Match each bearing from Column I with the graph in Column II that correctly represents the direction of that bearing, ensuring the clockwise measurement from north aligns with the graph's direction.

Understanding Bearings

Bearings are a way to express direction using degrees measured clockwise from the north direction (0° or 360°). They are commonly used in navigation and surveying to specify precise directions, typically ranging from 0° to 360°. Recognizing how bearings correspond to compass directions is essential for matching them to graphical representations.

Interpreting Angular Measurements on Graphs

Graphs representing bearings often use angles drawn from a reference line, usually the vertical north line. Understanding how to read these angles on a graph, including clockwise rotation and quadrant placement, helps in correctly associating a bearing measure with its visual depiction.

Relationship Between Bearings and Coordinate Axes

Bearings relate to the standard coordinate axes where north corresponds to 0° or 360°, east to 90°, south to 180°, and west to 270°. Knowing this relationship allows one to translate between bearing angles and their positions on Cartesian or polar coordinate graphs, facilitating accurate matching of bearings to graphs.
