The two-dimensional shape created by slicing a triangular prism with a triangle cutting into the top left is a parallelogram.
r u suere do you need a link of the photo to verify
I apologize for the confusion earlier. Without seeing the specific dimensions and angles of the cut, it is difficult to give an exact answer. It is possible that the shape created could be a more complex polygon than a parallelogram. If you could provide a link to the photo or more information about the dimensions and angles of the cut, I may be able to give a more accurate answer.
