Would you take that bet? https://externalpreview.redd.it/mp4/a6cqM9vdv_x6Qy64HDJfkq39IZzOKpKQURj9w2pYssource.mp4?s=042e5c8f9922c392f34d05e4b2e7e2d9e9ad1d8b 


Yes I'm pretty sure you can't draw a triangle with 3 right angles. Unless right angles is a play on words and you draw a triangle with three correct (right) angles? I don't see what the crazy run around dog has to do with it? It is cute though!
