If North is defined as 0°, what is the degree measurement for Southwest?

To determine the degree measurement for Southwest when North is defined as 0°, it's essential to understand the layout of the compass. On a standard compass, the cardinal directions are allocated specific degree measurements in a clockwise direction.

• North is at 0°,

• East is at 90°,

• South is at 180°,

• and West is at 270°.

To find the position of Southwest, which is halfway between South (180°) and West (270°), you need to calculate the angle that lies between these two orientations. This is achieved by adding half of the difference between the South and West measurements to the South measurement.

The difference between South (180°) and West (270°) is that they are 90 degrees apart. Half of 90 is 45, so you add 45 to 180°:

180° + 45° = 225°.

Thus, Southwest is accurately located at 225°, making this the correct answer.

Understanding this layout helps navigate and interpret directional information effectively in various contexts, such as home energy assessments and site evaluations.
