Sharing a Catriona Shearer geometry puzzle with my son – part 18

We went back a few months for our project with Catriona Shearer’s puzzles tonight:

My son was able to solved this problem. He presented his solution here:

After he finished his presentation we went to the titter thread to find a solution he liked. He chose this really nice one:

He explained this solution here:

My plan is to look at one more of Catriona’s puzzles tomorrow and then return to his Precalculus studies next week. I’ve really enjoyed this project and think that the combination of trying to find a solution on his own and then explaining one of the solutions from the original twitter thread has been a great way for my son to study geometry.
