I saw that in the challenge and was like Golden Triangle? Perfect Mashup of ISO/Aperture/Shutterspeed? Not a clue what it means. But excellent capture 👏
I would say you nailed it. Your fork runs diagonally from corner to corner, and if you draw an imaginary line from the top right corner to the top middle of the curve of the fork, it makes the required triangle.
It works!! Well done!!
