# What does a perpendicular line look like?

Two distinct lines which intersect at each other at 90° are called perpendicular lines.

## Answer: Perpendicular lines in math are two lines where the angle between them is 90°.

A perpendicular is a line that makes an angle of 90° with another line.

**Explanation:**

Perpendicular lines in math are two lines where the angle between them is 90°. The symbol used in between the two lines to say that they are perpendicular is \( \mathbf{\perp}\)

If two lines \(\overline{AB}\) and \(\overline{CD}\) are perpendicular to each other, we represent it using the notation \(\overline{AB} \perp \overline{CD}\).
