Joctee, in a right-handed system, positive angles produce counter-clockwise rotations when the origin is viewed from a positive axis; the opposite is true of left-handed systems. For example, if you’re looking down the positive z-axis, at the origin, a positive rotation would rotate the x-axis (east) towards the north.
