Two lines cannot be parallel and perpendicular at the same time.
They are not.
Parallel is when they are facing the same way eg. | | OR - -
No.
Depending on the value of the slope or gradient if its the same then they are parallel if its a reciprocal then they are perpendicular.
no, because parallel is opposite to perpendicular
Two lines cannot be parallel and perpendicular at the same time.
They are not.
Yes. Adjacent sides in a cube are perpendicular and planes that are perpendicular to the same plane are parallel.
Parallel is when they are facing the same way eg. | | OR - -
parallel
Yes they are. It's a postulate: In a plane two lines perpendicular to the same line are parallel.
No.
If they have the same slope, they are parallel. The slopes are the same, so yes they are parallel.
Two lines are parallel if and only if they have the same slope. Two lines are perpendicular if the product of their slopes is -1. If neither of these conditions are met, the lines are nether parallel, or perpendicular.
Depending on the value of the slope or gradient if its the same then they are parallel if its a reciprocal then they are perpendicular.
They are parallel to each other.
