Small challenge
Hello,
While making an Android app, I had to draw a small equilateral triangle pointing to a circle: ![[Image: DhKDFkB]](http://imgur.com/DhKDFkB) r: Outer Circle Radius: distance OAB d: Side length of the equilateral triangle. d=a*r, where a is a fraction of the outer circle radius If we want the distance AB to be equal to 1/5 of r, what's the value of a ? Have fun & Thanks for reading
