लंबवत (en. Perpendicular)

By adjusting the geometry of the reactor it is possible to synthesize vertically aligned carbon nanotubes (i.e., perpendicular to the substrate), a morphology that has been of interest to researchers interested in electron emission from nanotubes.

3. The screw is perpendicular to desk when it is upside down, especially the thread part.

Corner models beds, when one tier is perpendicular to another, solves the problem of saving space only partially, but it allows to provide the lower floor with natural light, which is good when equipping it with a desk.

So, the perpendicular to the wall the velocity is zero, this component disappears, so we can write this in the form as shown here.

In the second case, it is important to dock the boards of perpendicular walls in much the same way as when wallpapering is glued.

So, this is just a schematic diagram of the hard disc drive that employs some perpendicular magnetic recording medium and also shows such kind of inducting right and magnetoresistive reading heads.

Vertical, right-angle (perpendicular (90°)), coplanar (horizontal).
