      I know there’s math for this and it’s probably a relatively simple equation, but I’m trying to brute force it by calculating the area of each triangle assuming it’s a 3*6 grid.

      It’s a slog.

      Edit: Also I got stuck. The white part of the flag is the sum of a triangle roughly 1•6.32•6.7, and one roughly 5•2•6.7, but I forgot how to calculate the areas of scalene triangles. I know you have to make two right triangles out of them next, but I don’t know how to do that without just guessing and checking against the Pythagorean theorem, which is way more math than I want to do without a pencil and paper

        Well, you can calculate the areas of blue triangles easily since they’re right triangles, than just calculate pink+blue area and substract the blue area that you calculated previously, repeat for white+pink+blue.

        assuming it’s a 3*6 grid

        Yep

          Yup, I shouldn’t have started with white, lol

          Blue: (.5(2•3))+(.5(1•6))=6

          Pink: ((.5(4•3))*(.5(2•6)))-6=6

          White (simplified): (3•6)-12=6

    I love the Seychelles flag, because it’s a perfect transition between the Romanian and the Hungarian flag, two countries that (in good Balkans custom) basically hate each other.
