Twenty Questions (Of Maddening, Delicious Geometry) – Math with Bad Drawings
I came across Catriona Shearer‘s math puzzles on Twitter a few months ago. I was immediately drawn in: they’re so tactile, so handcrafted, so ripe for solving. Each of her gorgeously tricksy problems can swallow an hour in a single bite. She agreed to let me brainfish you folks by sharing 20 of her favorites. She even indulged my curiosity and admiration with an interview (see the bottom of the post). Enjoy. 1. “Unfortunately, my favourite one of the six is the only one I didn’t come up with myself,” says Catriona, “the dark blue one.” 2. (This one feels like an instant classic to me.) 3. “A ‘second attempt’ puzzle that was nicer than the first one I came up with.” 4. “I quite like this one – I drew lots of pretty patterns based on it.” 5. “Probably my all-time favourite. 6. “Another corollary that I much prefer to the original.” 7. “I find angles puzzles much harder to write. 8. “I never learnt the intersecting chords theorem at school, so I love anything where I get to use it!” 9. 10. 11.
