Mary says the pin for her horse is an acute right triangle is that possible? Explain.

Yes the pin for Mary’s horse is acute because a right angle is a corner of a paper, don’t ask how I’m saying this. It is acute because it is like how do I say this bent really if it is bent like a right angle you would know because the corner would look like this it would be bent like that and it would be a right angle if it was like this paper oh btw the pencil holder is acute and the paper is a right angle
