Two discs of radius one and a disc of radius one half are drawn on a plane so that each of them is touching the other two at one point–think of two quarters and a penny all flat on a table and all touching at their edges. Find the radius of the largest circle which is tangent to all three of the circles which are the edges of the discs.
