The phrase "to be perpendicular" refers to the relationship between two lines or surfaces that intersect at a right angle (90 degrees). It is commonly used in geometry and physics to describe angles and orientations in space. The term can also apply in broader contexts, referring to conditions where something is upright or vertically aligned.
Frequency of use tends to be more common in written contexts, especially in academic, mathematical, or scientific discussions, though it may appear in oral presentations where precision in describing geometric or spatial relationships is necessary.
Две линии на графике считаются перпендикулярными, создавая прямой угол в точке их пересечения.
For a structure to be stable, the walls need to be perpendicular to the ground.
Чтобы конструкция была устойчивой, стены должны быть перпендикулярны земле.
In this experiment, we need the laser beam to be perpendicular to the surface of the water.
The phrase "to be perpendicular" is not commonly used in idiomatic expressions. However, other terms relating to "perpendicular," such as "to stand upright," "to stand on end," or "to intersect at right angles," have their idiomatic uses.
Небоскреб, казалось, стоял прямо на фоне неба, доминируя над видом.
In a perpendicular alignment, the two roads would cross each other at right angles.
В перпендикулярном расположении две дороги будут пересекаться под прямым углом.
The engineer ensured that each beam would stand on end to provide maximum stability to the structure.
The term "perpendicular" originates from the Latin word "perpendiculāris," derived from "perpendiculum," which translates to "a plumb line." This indicates the vertical alignment aspect of being perpendicular.
