Question

Two lines are perpendicular if they intersect each other at

• A. acute angle
• B. right angle
• C. obtuse angle
• D. None of these

Answer 1

The correct option is B

right angle

Option B is the correct option.

When two lines intersect each other then they are perpendicular to each other.

They form $90°$ angle at the point of intersection.

And $90°$ is the measure of right angle.

So, Two lines are perpendicular if they intersect each other at right angle.
