Question

In the figure two lines AB and CD are intersected by a transversal ĺ such that <1 = 50°and <2 =
130°. Prove that AB and CD are parallel.​

Answer 1

Answer:

Given <1=50 and <2=130 degrees

Step-by-step explanation:

Angle1 +Angle 3=180( linear pair angles)

=>50+<3=180

=><3=180-50=130

Since <2 and <3 are corresponding angles which is only possible in parallel lines

Therefore AB ||CD

Hence proved
