Answer 1

Answer:

hey pls mark my answer as brainliest pls

so here we go

Step-by-step explanation:

your answer is yes

ie ad is parallel to bc

because here angle dab and bac forms a pair of corresponding angles and as they are each 90 degree ie are both congruent

ad and bc would be parallel as corresponding angles when are equal the lines are parallel

or u can also prove it by interior angles theorem for parallel lines as angle dab+cba=90+90=180
