Question

prove that a b parallel to CD
gave meaning full answer you will mark at brain list ​

Answer 1

Step-by-step explanation:

1) Extend DC and join to BE at X.

2) Now angle CEB = 54°

3) AB || EF (ABE = FEB)

4) In Triangle CEX,

CEX + EXC = PCE

24° + EXC = 150°

EXC = 126°

5) EXC + BXC = 180° ( Linear Pair)

BXC + 126° = 180°

BXC = 54°

6) let BX be Transversal

BEX = BXC = 54°

AB || DX

So, DC is also parallel to AB
