Question 34
AB01How many degrees are there on a compass card?
AI Explanation
The Correct Answer is A
### Why Option A ("360°") is Correct:
A compass card is based on the concept of a full circle. A full circle, by universal geometric definition, contains exactly 360 degrees. The compass uses this 360-degree system for angular measurement, starting at North (0° or 360°) and increasing clockwise through East (90°), South (180°), and West (270°), before completing the circle back at 360°.
### Why the Other Options Are Incorrect:
**B) 380°:** This is incorrect because 380° is more than a full circle (360°). If a compass had 380 degrees, the final 20 degrees would redundantly overlap the first 20 degrees of the card, violating the standard structure of angular measurement.
**C) 390°:** This is incorrect for the same reason as 380°. It exceeds the 360 degrees required to represent a full circle.
**D) 420°:** This is incorrect as it significantly exceeds 360 degrees. A compass card only needs 360 degrees to define every possible direction relative to a fixed point.
