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.

Q: How two lines that are each perpendicular to a third line can be perpendicular to each other?

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.

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.
