# Maximizing a triangle

I'm curious... Is it true, and, if so, is it straightforward to show that the maximum area triangle that can squeeze between these circles is equilateral?

Sort by:

You can model this on a co-ordinate grid, circles of radius 1 centered at (0,-1) and (+-1, $$\sqrt{3}-1$$). I couldn't really get anywhere, though. Probably a geometric solution is optimal, but I've never been good at those.

How a triangle can have curved sides

It can't have curved sides... I am talking about squeezing a triangle (which has straight sides) in that little space in the middle (which has curved sides).

Actual Yes

Sounds good... Do you know how to show it?

Yes The area of all 4 circles are equal to the area of the 4 triangles
