First page:
Angles B and C >>> vertical angles
C + D is 180 because they form a >>> straight line
D and E are congruent bc they are alternating interior.
Second page:
If A = 72 degrees, then D is 72 degrees. E and G would also be 72 degrees.
If A = 72, just remember that A + B = 180 (bc together they are a straight line), so 180-72 = 108. So Angle B is 108 degrees.
If B is 108 degrees, then C, F and H are also 108 degrees.
So the actual questions in the order listed:
B = 108 degrees
D = 72 degrees
E = 72 degrees
F = 108 degrees
H = 108 degrees
G = 72 degrees
