Using the information given, select the statement that can deduce the line segments to be parallel. If there are none, then select none. when m < 7 = m < 1

- AB || DC
- AD || BC
- None

Answer with explanation:

→If , AB ║ CD and AD  ║ BC

∠2 + ∠ D=180°(1)

→DA is a line.So, By linear pair

∠1 + ∠ 2=180°(2)

Equating (1) and (2)

∠1 + ∠ 2=∠2 + ∠D

Cancelling , ∠2 from both sides, gives

→∠1=∠D, is true statement.

You can also write Directly that, (∠1 and ∠D), and (∠3 and∠B), are corresponding angles, as lines are parallel,then corresponding angles are equal.
