I want to swing this triangle around on that green axis.
or some way of accomplishing the same thing. I just need to flip the triangle on its longest side. as you can see me attempting to do in this gif animation.
I haven't found a way of doing it without distorting the shape of the triangle. and I don't want to just eyeball it by trying to pull the corner into place. I want it to be exactly the way it was only flipped.
