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).

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).
