If your forward heading is 45°, what is your back-bearing?

Back bearing is the direction you’d travel to go from the far end back to where you started, which is exactly opposite your forward heading. Bearings are measured clockwise from north, so to reverse direction you add 180 degrees. With a forward heading of 45°, adding 180° gives 225°. That points in the opposite direction (southwest) along the same line. The other options don’t line up with the same line: 135° would be a different direction (southeast), 45° is the original forward direction, and 180° is due south, not the opposite of 45°.
