## The Solution to the Matchstick and Square Puzzle

It’s been three months since I posted the Matchstick and Square puzzle. According to one of the comments, it’s already causing household arguments., so I think it’s high time that I post my solution. There is no key to the puzzle, I only found it on a Facebook Page.

Please check if my solution below is correct. 🙂
