## 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: ⊥ ⊥ .

**What are perpendicular lines answer?**

Correct answer: Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.

**What do perpendicular lines imply?**

Lines that are at right angles (90°) to each other.

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

Perpendicular lines intersect at right angles to one another. To figure out if two equations are perpendicular, take a look at their slopes. The slopes of perpendicular lines are opposite reciprocals of each other.

**How do you show perpendicular lines?**

Explanation: If the slopes of two lines can be calculated, an easy way to determine whether they are perpendicular is to multiply their slopes. If the product of the slopes is , then the lines are perpendicular. In this case, the slope of the line is and the slope of the line is .

**How do you find perpendicular lines?**

#### Can lines be perpendicular and not meet?

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.

**How do you tell if a line is perpendicular to a plane?**

A line is perpendicular to a plane when it extends directly away from it, like a pencil standing up on a table. It can’t point anywhere else but directly away from the table. When a line is perpendicular to two lines on the plane (where they intersect), it is perpendicular to the plane.

**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.

## What are some examples of a perpendicular line?

**What is true about perpendicular lines?**

Steps to calculate a perpendicular line Calculate the slope of the original line. This can be done through the use of two points along the original line. Take the reciprocal of the original slope. Calculate b, the y intercept of the new line using the new slope and the point given along that line. Put all of the information together in point slope form.

**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.
