Using Catriona Shearer’s geometry puzzles with my younger son day 2

I’m going to spend a few – and hopefully many – days reviewing geometry with my younger son with the help of Catriona Shearer’s amazing geometry puzzles. You can follow along with our progress by using the Catriona Shearer tag in the blog or just searching for her name.

Today’s puzzle was from December:

My son was able to solve this puzzle and his solution is in the video below. I’m always really happy to see how careful he is with the details as he works through problems – this trait did not come from me!

After he solved the problem we went to the twitter thread to find a solution (hopefully different from his) that he thought was interesting. As with our first project from last night, he chose the solution from Nèstor Abad:

Here’s his presentation of Abad’s solution. Again, I’m happy that he was make to make (and understand) the details of the arguments with similarity and congruence:

I’m really happy with how this project went today – looking forward to another one tomorrow!
