Getting the angle between 2 CFrames

I have a CFrame cf and I want to calculate the angle between its rotation and the identity rotation (0, 0, 0). How would I go about doing this?

The idea of a single angle describing a CFrame transformation on its own doesn’t make sense mathematically. Maybe you’re looking for:

  • A single angle between one vector and another; or
  • An axis-angle representation of a CFrame/transformation; or
  • The set of (3) angles to apply in a particular order to construct (the rotational part of) a CFrame?

Sorry, I meant the angle between 2 vectors.

There are a lot of posts that have answered this already (searching for ‘angle between vectors’ will pull them up). For example:
