in 3d space. One line x=2. second line y=2. Third line z=2. They are all perp to one another.
=====================================
I have a set of lines like that in my bedroom, in the corner, where two walls meet the floor !
But, like, man, x=2, y=2, and z=2 aren't lines in 3d space, they're planes.

The second answer is correct. The equation of the x-axis is y = 0 and z = 0. The other axes can be defined similarly.
Alternatively, the equations can be defined in vecor form.
Each of the four lines is perpendicular - to two of the other lines.
Perpendicular lines intersect at right angles to each other.
It is impossible for parallel lines to be perpendicular. Perpendicular lines are intersecting lines, meaning that they cross each other. Parallel lines, on the other hand, are lines that never meet, no matter how far they are extended in either direction. So intersecting lines (which includes perpendicular lines) and parallel lines are exact opposites. Parallel lines will never meet or cross; they cannot be perpendicular.
The lines that meet at right angles are perpendicular to each other.
They are perpendicular lines
TRUE:: The first two lines lie in the same plain, but are perpendicular to each other. The third line passes through the plane of the first two lines so it is also perpendicular. Think 3-dimension. !!!!!
Perpendicular lines can not be parallel to each other but they can be to other lines.
Each of the four lines is perpendicular - to two of the other lines.
perpendicular lines run at 90% angles to each other not Parallel
Perpendicular lines intersect at right angles to each other.
Lines that intersect each other at right angles are called perpendicular lines

Perpendicular lines intersect each other at 90 degrees
The lines that meet at right angles are perpendicular to each other.
Perpendicular lines intersect each other at 90 degrees but parallel lines never touch each other
They are perpendicular lines
Perpendicular lines meet each other at right angles as for example the plus sign +
