Lines a,b,c, and d are in the same plane. Line a is parallel to line c. Lines b and c are perpendicular to line d. Based on this, tell how lines A and b are related. Justify your answer.
Given that lines a, b, c, and d are in the same plane. Line a is parallel to line c. Line b and c are perpendicular to line d. Therefore, we can say that lines a and b are parallel to each other. Both line a and b are perpendicular to line d.
