Sharing a Catriona Shearer geometry puzzle with my younger son part 7

This is part 7 of our series of walking through some of Catriona Shearer’s geometry puzzles. I’m really happy with how this is going and how her puzzles are helping my son learn about geometry.

Here’s the puzzle we looked at today:

My son’s solution was pretty heavy on computation, but he realized that there was an easier approach after he finished explaining the computation. That realization was nice to see!

The solution we looked at from the problem’s twitter thread was from Amerish G S. This solution was similar to what my son had done, but different enough that he learned a bit talking through it. That also make me happy – I love how great the twitter threads are following Shearer’s puzzles!
