Question

can any one help me understanding this???? ​

Answer 1

Answer:

if u can prove the angles BDC and angle DBA to be equal it will get parallel .

Answer 2

Answer:

Prove that angle ABE and angle BDC are equal

Step-by-step explanation:

We know,

angle AED= angle BAE + angle ABE [Ext angle property].....(i)

Given,

angle AED= angle BDC + angle BAE

•°• From (i),

angle BAE + angle ABE = angle BDC + angle BAE

angle ABE = angle BDC [Cancelling angle BAE on both sides]......(ii)

•°• Since, the alternate angles are proved equal in (ii) ,

AB || BC [Proved]
