Answer:

option a

Explanation:

AD and DE are perpendicular lines, meaning they are at a 90° angle. likewise, AD and AB are also perpendicular lines. this means that there are 90° angles at ∠ADE and ∠DAB.

since both DE and AB are perpendicular to the same line and are positioned at the same angle away from it, they are parallel lines.

i hope this helps! :D
