# What are two lines that are perpendicular?

**Two**parallel

**lines**won't ever intersect. If

**two**non-vertical

**lines**in the same plane intersect at a right angle then they are said to be

**perpendicular**. Horizontal and vertical

**lines**are

**perpendicular**to each other i.e. the axes of the coordinate plane. The slopes of

**two perpendicular lines**are negative reciprocals.

Consequently, what is an example of a perpendicular line?

**Perpendicular lines** are two **lines** that intersect in such a way that they have a right angle, or a 90 degree angle, between them. For **example**, **perpendicular lines** can be observed on floor tiles, on fences, on traffic signs, or on furniture. These are just a few **examples**.

One may also ask, how do I know if lines are perpendicular? Two **lines are perpendicular if** and only **if** their slopes are negative reciprocals. To find the slope, we must put the equation into slope-intercept form, , where equals the slope of the **line**.

Also Know, what makes a perpendicular line?

**Perpendicular lines** are **lines** whose slopes are negative reciprocals of one another. The **lines** intersect to form right angles. Negative reciprocals are two numbers that when they are multiplied together have product of -1.

What are some examples of perpendicular lines?

They are **perpendicular** because they cross at right angles to each other. If you look at them, they kind of make long rectangles. Another good **example of perpendicular lines** we can see in nature are a football field. All four corners of a football field are **perpendicular** to each other.
