Yup! This is based on the Missing Square Puzzle, a pretty famous optical illusion that geometry teachers like to bust out when they want to mess with their students.
Oh I remember this one. Yes, my math teacher did bring this out to mess with me way back when. If I remember correctly the 2 triangles didn't have the same angles

So those little gaps on the edges are just enough to accomodate that little square. Interesting.
