prove ab || ef
Plz tell it's urgent ​

Answer 1

Step-by-step explanation:

ABC =65°

Bcd=30°+35°=65°

THEREFORE ABC=BCD. (alternate angles ABC and Bcd are equal)

THEREFORE ABC||BCD

ECD=35°

E=145°

Ecd +E=35+145=180°

Therefore cd||ef (sum of Co interior angles Ecd and e is 180°)

Therfore ab||ef

Because two lines || to the same line are || to each other
