Euler angles, vector of <a href="//commons.wikimedia.org/wiki/File:Euler.png" title="File:Euler.png">File:Euler.png</a>. Drawing showing the elements of the rotation theorem.- Construction showing the theorem for a rotated sphere whose Euler angles are [ψ,θ,φ]. Frame in blue is attached to the fixed sphere. Frame in red is fixed to the rotated sphere. The line of nodes N determines the point A of the theorem. The arcs Aa and Aα must be equal
