Perpendicular Lines

In perpendicular lines when two intersecting lines a and b are said to be perpendicular to each other if one of the angles formed by them is a right angle.

In other words,

If two lines meet or intersect at a point to form a right angle, they are called perpendicular lines. We can draw a perpendicular line with the help of a set of square.

The symbol used for perpendicular lines are .

For example, a b (read as a is perpendicular to b).

Perpendicular Lines Ab and AC

In the above figure, AB and AC are perpendicular lines. ∠CAB = 90°. We use the symbol ⊥ to represent perpendicular lines.

What are perpendicular lines in geometry?

Lines that meet or cross at right angle are perpendicular to one another.

Perpendicular Lines

A right angle is usually marked by a box as shown in the above figure. Two rays or two line segments are said to be perpendicular if the corresponding lines determined by them are perpendicular. Similarly a ray and a segment are said to be perpendicular if the corresponding lines determined by them are perpendicular.

Here, l m (read as l is perpendicular to m).

Look at the following pictures and observe that how stumps of a wicket are placed on the ground. If we represent the ground by a straight horizontal line and a stump with a vertical line, the set of such lines are called perpendicular lines.

Perpendicular Lines Examples

Look at the two lines PQ and RS which intersect at the point P. 

Intersect at the Point P

These lines are perpendicular to each other.
