Which command would change a bearing from N 30° W to S 30° E?

• A. Translate
• B. Rotate
• C. Reverse
• D. Reflect

Answer: (C)

To get the opposite bearing, you need to point along the same line in the reverse direction. The bearing N 30° W means you’re 30 degrees west of north. The opposite direction along that line is 30 degrees east of south, which is S 30° E. The Reverse command flips the line’s direction by swapping its endpoints, so the bearing becomes the opposite one. Thinking in angles helps: N 30° W equals 330° from north; adding 180° gives 150°, which corresponds to S 30° E. The other tools don’t guarantee this opposite orientation: translating just moves the line, rotating would change orientation unless you rotate by 180°, and reflecting creates a mirror image that isn’t necessarily the exact opposite bearing.
