Perpendicular lines are two lines that intersect at a right angle, creating a 90-degree angle at their intersection point. They are the only lines that intersect a given line at right angles.
Think of them like the two hands of a clock. When they are perpendicular, their hands can never overlap or meet.
Here are some key characteristics of perpendicular lines:
They are parallel to each other but at right angles.
They have a constant distance from each other, regardless of the distance between the lines.
Any line that intersects both lines will intersect them at right angles.
They are colinear, meaning they lie in the same straight line.
Any point on one line will always be the same distance from both lines.
Examples:
The lines on a compass are perpendicular because they intersect at a right angle.
The lines on a ruler are perpendicular because they intersect at a right angle.
A line passing through the centers of two circles is perpendicular to both circles' radii.
The line from the top of a pencil to the base is perpendicular to the line from the bottom of the pencil to the point where it touches the ground
