Textbook Question

CONCEPT PREVIEW Match the measure of bearing in Column I with the appropriate graph in Column II. I. II.1. A. B. C. 2. S 70° W 3.4. D. E. F. 5.6.7. G. H. 8.9.10. I. J.

Verified step by step guidance

Step 1: Understand the concept of bearing. Bearings are used to describe direction and are measured in degrees from the North in a clockwise direction.

Step 2: Analyze the given bearing 'S 70° W'. This means starting from the South, measure 70 degrees towards the West.

Step 3: Visualize or sketch the direction. Start facing South, then rotate 70 degrees towards the West.

Step 4: Match this direction with the appropriate graph in Column II. Look for a graph that shows a line starting from the South and moving 70 degrees towards the West.

Step 5: Verify your choice by ensuring the angle and direction match the description 'S 70° W'.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Bearing

Bearing is a way of expressing direction in navigation and geometry, typically measured in degrees from the north direction. It is represented as an angle, with the first letter indicating the cardinal direction (N, S, E, W) from which the angle is measured, followed by the angle itself and the direction it turns (clockwise or counterclockwise). For example, 'S 70° W' means starting from the south and turning 70 degrees towards the west.

Graphical Representation of Bearings

Graphical representation of bearings involves plotting the direction indicated by the bearing on a coordinate system or compass rose. Each bearing corresponds to a specific angle, which can be visualized on a graph where the origin represents the starting point. Understanding how to translate a bearing into a graphical format is essential for accurately matching it with the correct graph.

Compass Rose

A compass rose is a figure on a map or chart used to display the orientation of the cardinal directions (North, East, South, West) and their intermediate points. It serves as a reference for understanding bearings and directions. Familiarity with the compass rose is crucial for interpreting bearings correctly and for visualizing how they relate to the various graphs presented in the question.
