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.
Lines that intersect at right angles, like in a plus sign (+).
lines, segments, or rays are perpendicular if they intersect to form a right angle
(4) Two rays, lines, or line segments that form right angles are said to be perpendicular to each other.
When two lines or line segments intersect and form right angles.
two segments or lines that intersect to form right angles.
A straight line or other vertical object is said to be in a perpendicular orientation when it is intersecting another straight line, plane, surface, or horizon at right angles (90°).
1. Intersecting at or forming right angles 2. At right angles
Meeting of a given line or surface at right angles.
Two lines are perpendicular if the angle between them is 90 degrees.
Erroneous Idea that Major Relationships are at 90 Degree Angle
A line or plane at a right angle to a given line or surface.
Two intersecting lines are perpendicular if they form a right angle (a 90 degree angle).
Lines in the same plane which intersect to form a right angle.
A ninety degree angle formed by two lines.
When a straight line stands on a straight line and makes the adjacent angles equal to one another and at right angles, the straight line standing on the other is called the perpendicular to the other.
Something abutting at a 90-degree angle to something else.
at right angles to a line or plane
a term describing two lines or line segments that cross to form a right angle.
Two lines that form a right angle (90 degrees). Their slopes are negative reciprocals of each other. (The product of their slopes is -1)
Two rays, lines, line segments, or other figures that form right angles are said to be perpendicular to each other. The symbol ^ indicates perpendicular figures.
characterized by an angle of intersection which is a right angle, typically in reference to a two-dimensional figure; in higher dimensions this property is usually referred to as "orthogonality" (being orthogonal)
Positioning of a member so that it projects out from or crosses another at a right angle. Compare to parallel and transverse.
Situated at right angles to the plane of the horizon, or directly up or down; vertical.
Intersecting at or forming a right angle; a 901/4 angle.
Two lines, vectors, planes, etc. that intersect at a right angle.
Two lines, segments, or rays that intersect to form right angles.
Two lines which intersect to form a right angle.
At right angles (90 degrees) to a given plane or line.
In geometry, two lines or planes (or a line and a plane), are considered perpendicular (or orthogonal) if one falls on the other in such a way as to create congruent adjacent angles. The term may be used as a noun or adjective. Thus, referring to Figure 1, the line AB is the perpendicular to CD through the point B.
