Question

if a trnasversal intersects two lones such that the bisector of a pair of corresponding angle are parallel then prove two lines r parallel

Answer 1

Answer:

If a transversal intersects two lines such that the bisectors of a pair of corresponding angles are parallel then prove that two lines are parallel

But these are corresponding angles. We know that if a transversal intersects two lines such that a pair of corresponding angles is equal, then the two lines ate parallel to each other. Hence, AB║ EF Proved.

Answer 2

Answer:

given: A transversal AB intersects two lines PQ and RS such that ∠ PLM = ∠ SML

To prove: PQ || RS

Proof: ∠ PLM = ∠ SML (given) ....... (i)

∠ SML = ∠ RMB ....... (ii) (vertically opposite angles)

From equations (i) and (ii),

∠ PLM = ∠ RMB

As these are corresponding angles and corresponding angles equal only if given lines PQ and RS are parallel.

∴ PQ || RS
