How do you draw a triangle with 3 right angles?

Answer 1

This cannot be done as all angles in a triangle must add up to 180 degrees. A right angle is 90 degrees and so three right angles would equal 270 degrees meaning the lines could not meet up. This is also the same for making a triangle out of two right angles as the angles would add up to 180 degrees without the final line meaning it would have to go past 180 degrees
