How does 3 rights make a left?

Answer 1

Think of a compass rose, where you're facing north. Turn right 3 times, so you're facing the west, which is the left.

Or, if you start in a neutral position, and consider each turn to be worth rotating 180o, then turning right 3 times would be facing right and then rotating (clockwise or counter-clockwise) 360o 3 times would end up pointing you to your left.

Answer 2

The phrase "3 rights make a left" is a mnemonic device used in navigation to help remember that making three right turns is equivalent to making a left turn. This concept is based on the fact that a complete circle is equivalent to 360 degrees, so making three 90-degree right turns effectively turns you 270 degrees to the left. This principle is commonly used in driving directions or when navigating through a maze-like environment.
