Question

In the below figure "l" and "m" are two lines intersected by a transversal "n" If 1=130° and 8=50° then is l//m ? state the reason ​

Answer 1

Answer:

Yes

Step-by-step explanation:

∠4 + ∠ 1 = 180° (linear pair)

∠4 = 180° - 130°

     = 50°

⇒ ∠4 = ∠8

But ∠4 and ∠8 are corresponding angles, which proves that l//m.
