Respuesta :

Part A

It is given that

AK⊥ KB

AK║EF

AK║CB

1.⇒∠AKB=∠JFB=90°------Corresponding Angles, when lines are parallel corresponding Angles are equal.

3.

From (1),(2) and (3) we conclude that

 EF ⊥ KB

And ,CB⊥KB.

→Lines which are parallel and among one of them is perpendicular to a line, then all parallel lines will be perpendicular to that line.

Option (1) and (3)

Part(B)

QR and ST-----Parallel

ST and QS----Perpendicular

RT and QR----Perpendicular

QS and RT-----Parallel

Answer:

The anwsers are

1)   KB←→⊥CB←→

2) m∠JFB=90°
