# What is an example of a perpendicular line?

## What is an example of a perpendicular line?

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol used to denote two perpendicular lines: ⊥ ⊥ .

How do you describe perpendicular lines?

Perpendicular lines are lines, segments or rays that intersect to form right angles. The symbol ⊥ means is perpendicular to . In the figure, PR⊥QS. The right angle symbol in the figure indicates that the lines are perpendicular.

### What does perpendicular lines mean for kids?

right angle
The perpendicular line is a line that crosses another line at a 90° angle. Each corner meets at a 90° angle. This is also known as a right angle.

What does a perpendicular sides look like?

Perpendicular lines are two or more lines that intersect at a 90-degree angle, like the two lines drawn on this graph. These 90-degree angles are also known as right angles. o Look at the slopes of the two parallel lines.

#### What type of angle do perpendicular lines form?

90 degrees
Perpendicular lines are lines that intersect at a right (90 degrees) angle.

What are the three prove to show that lines are perpendicular?

If two lines intersect to form a linear pair of “congruent angles”, the lines are therefore perpendicular. Congruent angles are just angles that are equal to each other! If two lines are perpendicular, they will intersect to form four right angles.

## How do you know if a shape is perpendicular?

Squares and rectangles always have four right angles! A triangle will have perpendicular lines if it has a little square where two lines intersect to indicate there’s a right angle there or if someone tells you that the triangle is a right triangle. This is also true for trapezoids.

What do we call the two lines that never met?

In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.

### What pairs of lines are perpendicular?

Two distinct lines intersecting each other at 90° or a right angle are called perpendicular lines. Here, AB is perpendicular to XY because AB and XY intersect each other at 90°. The two lines are parallel and do not intersect each other. They can never be perpendicular to each other.

What is the major difference between parallel lines and perpendicular lines?

In geometry, two lines are said to be parallel if they are equidistant and will never intersect. If two lines intersect at a right angle then they are said to be perpendicular.

#### Can two lines with positive slopes be perpendicular?

is not possible for two lines with positive slopes to be perpendicular to each other.

What are examples of perpendicular lines?

Football field

• Railway track crossing
• First aid kit
• Construction of a house in which floor and the wall are perpendiculars
• Television
• Designs in windows
• ## Which lines are perpendicular?

Perpendicular Lines Symbol. Perpendicular lines are represented by the symbol, ‘⊥’. Properties. If any two lines are perpendicular to the same line, then they both are parallel to each other and never intersect. Slope of Perpendicular Lines. Suppose two lines AB and CD are perpendicular to each other. Construction of Perpendicular Lines. Examples. Problems and Solutions.

What are some real life examples of perpendicular lines?

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.

### How are perpendicular lines used in real life?

Real life examples of perpendicular lines surround us. They are in buildings, in rooms, television sets, bookshelves and so on. If you are in a room, more than likely you are surrounded by four walls that are all perpendicular to each other. Where they meet creates a line. The ceiling is perpendicular to all four walls, and so is the floor.
