Can someone take a look at https://github.com/sympy/sympy/pull/331/files ? We need to have RegularPolygon doing a proper rotation. It's about a 15 minute review, I would guess. This may help:
regular polygon has an angel attribute that needs a method to set that angle. I call (now) that method 'spin' which spins it ccw the angle given in order to rotate a regular polygon about a point by some angle, it's two steps: spin it by that angle then shift its center relative to the point by that angle, e.g. if you had a triangle centered at 1,0 with a vertex at 2,0 and you rotated it relative to the origin by 90 degrees you would expect it to now be centered at 0, 1 with a vertex at 0,2. -- You received this message because you are subscribed to the Google Groups "sympy" group.
