In the figure given below, state which lines are parallel and why ?

Text Solution

Verified by Experts

The correct Answer is:
`AB||CD, DE` not parallel to AC
Since `angleBAC=angleACD`, which are alternate angles, so `AB||CD`. But, `angleACD+angleCDE=(110^(@)+80^(@))=190^(@) ne 180^(@)`.
`:.` DE and AC are not parallel.
