Answer 1

Answer:

if a= 80° then,

a=c ( vertically opposite angles )

c=80°

a=e ( corresponding angles )

e=80°

e=g ( vertically opposite angles )

g=80°

g+h= 180° ( linear pair )

h=180-g = 100°

h=f ( vertically opposite angles )

f= 100°

f=b ( corresponding angles )

b= 100°

b=d ( vertically opposite angles )

d=100°
