"Right means clockwise" and "left means anti-clockwise"

This is only true when referencing the top of the object being rotated. Rotating "left" and "right" is incorrect for all other vertices.

Clockwise - Clockwise is the direction that the hands of an analogue clock travel.
Anti-clockwise - Anti-clockwise is the opposite direction to which the hands of an analogue clock travel.
Degrees - The most common unit of measurement for angle. One whole turn is equal to 360 degrees, written 360°.
