Hello, and welcome to Stack Exchange. Are you asking about the angle between the Earth's axis and its equator? They're defined as 90° apart...

I'm aware of equator-pole angle,  I wanted the angle between axis and equator. Thanks @DanielGriscom, your comment has answered the question.

@user1 Your question title and body both still mention "66 1/2 degrees" and you haven't stated why you think this figure might apply to the Earth, or why you think the axis might be at a different angle than the pole.

What is the angle between earth's axis of rotation and equator? Are they perpendicular or at 66 1/2 Degrees?

By rotational axis I mean axial tilt or Axial obliquity or 66 1/2 degrees tilt of earth to its orbital.
