The red field of the Nepalese flag consists of two overlapping triangles:

A...D

|\ .

| \ .

| \.

| E-F

| \.

B---C

where C and F lie on a vertical line. There is a blue border around this field which makes point F extend slightly further than point C when the entire flag is considered, since angle AFE is smaller than angle ECB. - Jeremy Tan, Apr 06 2015

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
