4) Which of the following lines are parallel to each other in the
figure shown?
A) Lines b and d
B) Lines a and b
C) Lines a and c
D) Lines a and d
5) Which of the following lines are perpendicular to each other
in the figure shown?

B) Lines b and a
C) Lines a and e
D) Lines a and

Step-by-step explanation:

Parallel lines are lines that never meet, from the question in the attachment above, the two lines that cannot meet are lines 'a' and 'b' and lines 'c' and 'd'

4. Question four is then lines b and a which is option B

Perpendicular lines are lines in which the angle between them is right angle (90 degrees). Which are 'a' and 'c', 'a' and 'd', 'b' and 'c', 'b' and 'd'

5. Question 5 is therefore 'a' and 'c' which is option D
