Is this a right triangle?

Right Triangle

Step-by-step explanation:

I apologize for my original answer not living up to your expectations. I myself was a bit confused. But I will now provide an explanation. The way the image is tilted, it does not seem like a right triangle. But it is. The coordinates imply something else, but they are a tease. If you look upon the triangle in another way, it will look, or become, straight. Hopefully this explanation is helpful. Once again, I apologize.
