COMMENTS

This is the ratio of the base of an isosceles triangle to its height when the other two sides are each equal to twice the base.
Exradius opposite the side of length 3 of the obtuse scalene triangle with sides of lengths 2, 3 and 4, the scalene triangle with least integer side lengths. See formulas in the Weisstein link. - Rick L. Shepherd, May 14 2008
