Hope you could understand.
If you have any query, feel free to ask.
If two adjacent angles have their exterior sides in perpendicular lines, then the two angles are also perpendicular.
Both exterior and interior angles sum up from 90 - 180 degrees. Therefore, if an exterior angle is perpendicular, then the interior angle must also be perpendicular in order for them to sum up to that amount of degrees (90 - 180).
I did it by the formula (a-b)^2=(a)^2-(2ab)+b^2
