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