Right angle representation
I need to underline that two segments are orthogonal, so I would like to show that the angle they form measures 90° degree. I created the angle and it showed up fine as a small square (see first attached image).
At a certain point, however, the representation of the angle changed and appeared as a round angle with a point inside it (see second attached image). I suppose this point is meant to indicate that the angle is exactly 90°, however this notation is not common for my students, and I would like to have my "square" angle back.
Is it possible somehow? I wasn't able to find the way to get it
Thank you in advance
