Let’s make another try:

Is this how angles are defined in a right-handed coordinate system?

Well it won’t work with the code block, so there will not be any nice ASCII art here.

But let me ask the question like this:

In a righthanded coordinat system:
Is 0 degrees north?
90 degrees west?
180 degrees south?
270 degrees east?

Well, my question wasn’t about the axis in a rh-cs.

Let me put it in this way,

If an object is heading north in a rh-cs. Has it an orientation of 0 degrees?

If the same model is heading west, has it an orientation of +90 degrees?

If the same model is heading south, has it an orientation of 180 degrees?

If the same model is heading east, has it an orientation of -90(+270) degrees?

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.
