Question

in the
given figure, AB II CD and EF is a transversal If angle1 = 120°, then find angle 2​

Answer 1

Answer: 60°

Step-by-step explanation:

If angle 1 = 120° (given)

Then,

Angle 1 = Angle MND = 120° (alternate angles)

=>Angle MND + Angle 2 = 180° (linear pair axiom)

=>Angle 2 = 180°-120°

=>Angle 2 = 60°

Answer 2

Step-by-step explanation:

given

AB||CD

EF is transversal

angle1=120°

to find =angle 2

solution

let angle BMN=3

angle 1+angle 3 =180°(linear pair)

120 +angle3=180

angle 3 =180-120

angle 3=60

angle 3 = angle 2(alternate interior angles)

60°=60°

angle 2 =60°
