During a rectangular course, a turn less than 90 degrees is typically associated with which corners?

• A. Corners 1 and 4
• B. Corners 2 and 3
• C. Corners 2 and 4
• D. Corners 1 and 3

Answer: (A)

The key idea is how the turn geometry works as you switch from one leg to the next on a rectangular course. When you reach the corners on the inner side of the rectangle, the next leg is already close to your current direction, so you can roll into the turn with a shallower angle—less than a 90-degree change. At the outer corners, you must swing out more to reach the next leg, needing a larger-than-90-degree change. So the corners where you typically make a shallower-than-90-degree turn are the two inner corners of the rectangle.
