1= 135 3= 45 6= 45 3 and 6 are congruent/equal to angle 2, so they’d measure the same. since 1 and 3 are on the same line and that line equals 180 degrees, i did 180-45 to get angle 1.
This is because angle two and 6 are corresponding angles. you would then subtract 180 from 45 because angle 6 and 4 are consecutive angles. This would give you 135 degrees. Then angle 1 and angle 4 are verticla agles, making them equal to each other.
