Question

Given that angle ABC=70° and that angle BCD=110°. Is it possible (consider all cases) that Line AB is parallel to line CD ?

Answer 1

Yes. AB is parallel to line CD. The “same side interior angles” theorem applies to this problem. I hope this helps you

Answer 2

Answer:

no

Step-by-step explanation:

Since ∠ABC=70 and ∠BCD=110, BC is common line

AB can't be parallel to CD as ∠ABC≠∠BCD

the answer is no
