Question

8. In the given figure, show that AB | EF.
A
75°
140°
35°,
40°
C​

Answer 1

Answer:

In the figure ,

∠ABC = 65°

∠BCD = 32° + 33° = 65°

∴ ∠ABC = ∠BCD [Alternate Interior angles ]

∴ AB || CD ................................ (1)

∠ CEF = 148°

∠ DCE = 32°

∠ CEF + ∠ DCE = 180°

148° + 32° = 180° [ Interior angles on the same side of the transversal ]

∴ CD || EF ........................................(2)

From (1) and (2) ,

AB || EF
