Question

who knows about parallel line proofs??

Answer 1

There is something wrong with this question
BD is not parallel to AD (they meet at D, and parallel lines do not meet)
if they mean show BC || AD you can do that

Answer 2

BE=DE definition of bisector
CE=AE definition of bisector
angle BEC=angle AED vertical angles
therefore triange BCE=triangle DAE Side-angle-side
therefore angle CBE=angle ADE CPOCT
therefore BC II AD corresponding angles

Answer 3

thanks
