MCQ
The two lines which are perpendicular to the same line are _______ to each other.
- AEqual.
- ✓Parallel.
- CPerpendicular.
- DNone of these.
✓
Answer
Correct option: B.
Parallel.
If a transversal cuts two different lines and if the sum of the corresponding angles is equal to $180$ degrees. Then, the two given lines are parallel to each other and here, both the lines are perpendicular to the transversal. So, the sum of angles made by them on the transversal is 180 degrees. Hence, both the given lines are parallel to each other.
