Which of the lines are perpendicular to each other?
Let's remember that perpendicular lines are lines that form a right angle of 90 degrees between them.
In each of the answers, we will draw the letter T at the point of intersection of the lines.
Let's examine figure A:
We will notice that the lines do not form a right angle, and therefore are not perpendicular.
Let's examine figure B:
The lines do indeed form a 90-degree angle and are therefore perpendicular.
Let's examine figure C:
We notice that the lines do not form a right angle, and therefore are not perpendicular.
