a. 108°
b. 72° - it forms a straight line with <a. a straight line has a degree of 180. 180-108 is 72
c. 108° - <c is an opposite angle of <a. opposite angles are always equal.
d. 72° - <d is an opposite angle of <b. so the measurement of it is 72° also.
e. 108° - <a is the corresponding < of <e. corresponding < are always equal.
f. 72° - it forms a straight line with <e
g. 108° - it also form a straight line with <f, it is also a corresponding angle of <c
h. 72°- forms a straight line with <e, also a corresponding < of <d
