Exactly upright or vertical; pointing to the zenith; at right angles to the plane of the horizon; extending in a right line from any point toward the center of the earth., At right angles to a given line or surface; as, the line ad is perpendicular to the line bc., A line at right angles to the plane of the horizon; a vertical line or direction., A line or plane falling at right angles on another line or surface, or making equal angles with it on each side.
perpendicular
Lines that intersect each other at right angles are called perpendicular lines
No, the diagonals of a rectangle are not perpendicular. The angles between them depend on the dimensions of the rectangle.However, the diagonals of a square are perpendicular (and squares are technically "regular" rectangles, meaning that all sides and angles are equal).
It is difficult without more context but I am guessing that it refers to Perpendicular Height.
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.
perpendicular. meaning that they make a right angle when they cross
The opposite (perpendicular direction) of vertical is horizontal, meaning side to side.
-- an angle that measures 90 degrees -- an angle whose sides are mutually perpendicular
S waves, or secondary waves, are transverse seismic waves, meaning that the particles being effected by the wave are moving perpendicular to the wave's propagation.
Perpendicular or 90 degrees to level (horizontal level)... In other words, straight up and down.
No . It is not perpendicular
yes it is perpendicular
