25 sie 2017 · This geometry video tutorial provides a basic introduction into perpendicular lines, slope, rays, line segments and right angles.
A line is said to be perpendicular to a plane if it is perpendicular to every line in the plane that it intersects. This definition depends on the definition of perpendicularity between lines. Two planes in space are said to be perpendicular if the dihedral angle at which they meet is a right angle.
In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90 ∘). The term ‘perpendicular’ originated from the Latin word ‘perpendicularis,’ meaning a plumb line. If two lines AB and CD are perpendicular, then we can write them as AB ⊥ CD.
Learn what perpendicular means in geometry and how to identify perpendicular lines, rays, segments and planes. Explore the properties and applications of perpendicularity with diagrams and examples.
We say that a line is perpendicular to another line if the two lines meet at an angle of 90 °. Let us understand the concept of perpendicular lines, the perpendicular sign, the difference between parallel and perpendicular lines, along with some perpendicular lines examples.
Parallel and perpendicular lines are two important concepts in geometry. Parallel lines are the lines that never intersect each other. Thus, two parallel lines always maintain a constant distance between them. Perpendicular lines are the two lines that intersect each other at a right angle.
Perpendicular lines are two straight lines that meet or intersect at 90°. The opposite of perpendicular lines are parallel lines. Unlike perpendicular lines, parallel lines never intersect. The equation of a line that is perpendicular is y = mx + c.
