Learn what are perpendicular lines, how to construct them, and their properties and examples. Find out the difference between perpendicular and parallel lines and real-life examples of perpendicularity.

Learn how to use algebra to find parallel and perpendicular lines with examples and exercises. Parallel lines have the same slope, perpendicular lines have negative reciprocal slopes, and vertical lines are parallel to themselves.

Learn what perpendicular lines are, how to draw them, and how to identify them. See the difference between perpendicular and parallel lines, and the symbols used to denote them.

Perpendicular lines are lines that intersect to form 90^{\circ} angles (right angles). In diagrams, right angles are often marked with a small square at the point where the two lines intersect. This notation helps us to quickly identify them as perpendicular lines.

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.

Learn the definition, properties and examples of perpendicular lines in geometry. Find out how to identify, measure and construct perpendicular lines using angles, slopes and equations.

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.

The definition of perpendicular lines states that when two lines meet or intersect each other, an angle of 90 degrees is formed.

Learn what perpendicular lines are, how to identify them, and how to use them in geometry and real life. Find out the symbol, measure, slope, and types of angles and shapes formed by perpendicular lines.
