The two lines that intersect one another at right angles (90°) are called perpendicular lines.
<h3>How can we identify perpendicular lines?</h3>
In math, the symbol ⊥ is used to indicate perpendicular lines. For example, if there are two lines EF and GH that intersect each other, we symbolize it with EF ⊥ GH.
In real life, there are many perpendicular lines that we usually see in the form of the letter "L." For example, the corner of a TV, a laptop, a door, or a watch that shows 3 or 9 o’clock.
To draw perpendicular lines, we can use a ruler, a compass, or a protractor.
In conclusion, the lines that intersect or meet each other are called perpendicular lines.
