Which lines are perpendicular to each other?
Which lines are perpendicular to each other?
Let's remember that perpendicular lines form a 90-degree angle with each other.
To check if the lines form a 90-degree angle, we will draw a T at each intersection as follows:
We notice that in each of the four drawings, the lines form a 90-degree angle.
Therefore all are correct as all the lines are perpendicular to each other.
All answers are correct.
