Explanation:
(a) < a = 180-55= 125
(b) < b = 180- 125= 55
(c) < c = 189- 55 = 135
(d) < e = 125
(e) < f = 180-125= 55
(f) < h = 55
~
< a and < c are vertical angles.
< a and < b are adjacent angles.
< b and <h are Alternate interior angles.
< f and 55° are Alternate Exterior angles.
< a and < e are corresponding angles.
