Question

In the given figure, l//m, find the unknown angles

Answer 1

since L||m

so
◆a=65° corresponding angle
g+65=180(straight line)
◆g=115°

g=d corresponding angle
◆d=115°


e=d alternate angles
◆e=115°

b=e(interior angles)

◆b=115°

◆c=65°

f=c (interior angles)
◆f=65°

Answer 2

a=65° ( corresponing angle)
f=a=65° ( interior alternate angles) or (vertically opposite angle)
c=a=65° (vertically opposite angle)
g=180-65=115° ( linear pair)
d=g=115° ( corresponding angle)
b=d=115°( vertically opposite angle)
e=g=115°(vertically opposite angle)




so
a=65°
b=115°
c=65°
d=115°
e=115°
f=65°
g=115°
