Question 174585
Do you have any way to copy the picture of what you are looking at. Hard to picture what R is.  If the HN and AO are the legs then the only midpoint of those segments would be a line between the two of them or a line that connects their midpoints and I dont see any reason why one leg cant be longer than the other it would just make at least one of the legs form an angle other than 90 degrees.
