Question
The distance between the parallel lines AB and CD of the parallelogram is _______.

- 4 cm
- 4.8 cm
- 6 cm
- 5 cm
Hint:
The distance between two parallel lines is the perpendicular distance from any point on one line to the other line. For two intersecting lines, the shortest distance between such lines eventually comes to zero and the distance between two skew lines is equal to the length of the perpendicular between the lines.
The correct answer is: 4 cm
The distance between two parallel lines is the perpendicular distance from any point on one line to the other line. For two intersecting lines, the shortest distance between such lines eventually comes to zero and the distance between two skew lines is equal to the length of the perpendicular between the lines.

From, the above figure AB
CD and line B
CD
Since, the distance between two parallel lines is equal to the length of the perpendicular segment between the parallel lines.
Thus, the distance between the parallel lines AB and CD of the parallelogram is 4 cm.
