#GeometryPuzzles After @loopspace wrote about his webpage with geometry puzzles in November (https://mathstodon.xyz/@loopspace/115561659405894319), I have from time to time gone to that page to solve a few puzzles. After a while, I started trying to create some puzzles on my own too. Then I thought I could post them here, in case anyone in the Fediverse might be interested in solving them. Here is my first puzzle: Two regular pentagons of the same size, each containing a quadrilateral (every point that looks like it could be the midpoint of a line segment is the exact midpoint of that line segment). How large is the pink quadrilateral relative to the blue one?
