angle(other)

canonical angle between vectors, angle(u, v) = u dot v / (|u|*|v|)

Is the angle between the lines generated by self and other.

Range is [0, pi]

v.angle(w) == w.angle(v)

angle_oriented(other)

signed angle from self to other

The angle to rotate self so that it points in the same direction as other

Range is [-pi, pi]

v.angle(w) == - w.angle(v)
