Nepal –
• All the flags usually have a rectangular shape, except for one. It is the flag of Nepal, which consists of two connected triangles which represent the peaks of Mount Everest. • The lower triangle is the symbol of the sun, and the higher the moon.Nepalese According to legend, this country will exist as long as there are these two celestial bodies.
Hopefully I could go to Nepal next year. We have solid plans for that.
Great Information here
The flag for the state of Ohio is not shaped like a rectangle either.
