Question

In which of the following situations an angle bisector cannot be constructed to bisect the angle formed between two given lines?

• A. Two intersecting lines
• B. Two parallel lines
• C. Two perpendicular lines
• D. None of the above

Answer 1

The correct option is B Two parallel lines

Since two parallel lines do not intersect each other, an angle cannot be formed between them. Thus in this case, angle bisection is not possible.
