Answer 1

Answer:

hey pls mark my suggestion as brainliest pls

I would just provide you the guidelines how to crack the logic

but representation is your work

Step-by-step explanation:

so we know that

to prove any two lines parallel

1.two lines are only parallel,when the sum of interior angles is supplementary

2.two lines are parallel,when the corresponding angles are congruent

3.and when alternate angles are equal

so for this physics problem

either prove

angle dba+angle bac=180

OR

angle dba=angle bac

so as to prove ray db parallel to ray bd
