# Examples of perpendicular lines in our surroundings

Perpendicular lines occur anytime two lines meet at a 90° angle, also known as a right angle. Sometimes, you will see a little square in the corner of an angle, to show it is perpendicular One common example of perpendicular lines in real life is the point where two city roads intersect. When one road crosses another, the two streets join at right angles to each other and form a cross-type pattern. Perpendicular lines form 90-degree angles, or right angles, to each other on a two-dimensional plane

### Perpendicular Lines Lesson for Kids: Definition & Examples

1. Perpendicular lines are represented by the symbol, '⊥'. Suppose, l1 and l2 are two lines intersecting each other at 90 degrees, then they are perpendicular to each other and is represented as l1⊥l2. The point of intersection is called the foot of the perpendicular
2. If two lines are perpendicular to the same line, they are parallel and will never intersect. Perpendicular lines always intersect, but the converse is not true; that is we can't say intersecting lines are always perpendicular. If two lines are perpendicularly representing the slope then m1 ×m2 = −1. m 1 × m 2 = − 1
