COMMENTS

The flag of Nepal consists of two overlapping triangles:
A...D
\ .
 \ .
 \.
 EF
 \.
BC
The bounding rectangle is then ABCD, and the ratio is AB/BC.
This constant is algebraic, specifically quartic. In particular it is the least root of 243356742235044x^4  1325568548812608x^3 + 2700899847521244x^2  2439951444086880x + 824634725389225.  Charles R Greathouse IV, Oct 24 2013
