Standard “they don’t know” meme format, featuring line art of “That Feel Guy” wearing a party hat standing in a corner while other people are dancing. An image of an icosahedron formed by three mutually perpendicular golden ratio rectangles sits in front of That Feel Guy. The caption text says “They don’t know that three mutually perpendicular golden ratio rectangles, with edges connecting their corners, form a regular icosahedron.”

    Is it because the golden ratio contains the square root of three which is used in constructing triangles in 3d?

    Wait no, it uses the square root of 5 plus one, that is pretty magical!

      I assume it’s because the GR has a ratio of the longer side to both sides summed. Although I can’t explain it further than that lol
