I am trying to make a neat charting app, yet I am having dificulty with some of the math. That's why I'm here!
I have a "pie slice" at a specific angle. I don't want the slice to just be a simple little pie-slice, no, I want to make it a cone shape!
Where do I place the circular cap? If I draw a triangle around my "pie-slice", I can see that the circle at the end must be tangent to all sides of the triangle. Whats the radius of that circle? Where's the center point? What are the points which are tangent to the "triangle"?
@1 (highlighted in blue), and
@2 (highlighted in green) are known, but how could I find
@3 (highlighted in red)?
