## What isperpendicular?

Two straight lines are perpendicular if, and only if, they are concurrent and form “right” angles. A line concurrent with a plane, at a given point, **is perpendicular** to the plane when **it is perpendicular** to all the lines in the plane that pass through the given point.

## What is an oblique line?

**Oblique lines**are concurrent

**lines**that form angles other than 90º. We use the symbol ∠ to indicate the

**oblique**condition . Notation: r ∠ s It reads:

**line**r

**oblique**to

**line**s. Perpendicular

**lines**are concurrent

**lines**that form right angles (equal to 90º).

## What is an oblique concurrent line?

**Concurrent lines** are defined as those that intersect at a single point, forming four angles. According to the measurements of these angles, they can still be considered perpendicular **lines** or **oblique lines** .

## What is a reverse straight line?

In geometry, two lines are considered reverses if, and only if: they do not intersect; are not parallel to each other.

## When are two lines reversed?

**Reverse lines are lines** that do not intersect between them and **are** not parallel. This means they are on different planes.

## How to classify straight lines?

**Lines**are flat or spatial geometric figures that can be classified as concurrent, coincident and parallel. In Geometry,

**lines**are defined only as sets of points.

## When are the lines parallel?

We know that **two straight lines are parallel** when **they are** equidistant throughout their length, having no point in common. Thus, consider **two straight lines** , res, in the Cartesian plane. … The straight **lines ****are parallel** if, and only if, they have the same slope or their angular coefficients are equal.

## How do you know if the lines intersect?

The point of intersection between **two straight lines** , or meeting point, can be obtained by equating the equations related to them or by solving the system formed. A **straight line** is a set of points **that** does not curve. On a **straight line** , there are infinitely many points, which **also** indicates **that** the **line** is infinite.

## How do you know if the lines are orthogonal?

**two straight lines are**perpendicular and we can identify them by analyzing the relationship between their angular coefficients. Thus, for

**two straight lines**to be perpendicular, the angular coefficient of one must be equal to the opposite of the inverse of the angular coefficient of the other.

## When are two lines orthogonal?

4 – **Orthogonal lines** – **are** reverse lines (and therefore **are** not coplanar), which form a right angle. Therefore, if **two lines** form a right angle, they will be perpendicular if they are coplanar or **orthogonal** if they are reverse.

## What is the difference between perpendicular and orthogonal lines?

The **difference** is that two straight segments that form a right angle **to** each other will always be **orthogonal** , but they will only be **perpendicular** if they touch at some point.

## How to prove that the lines are perpendicular?

**straight lines**are

**perpendicular**if they intersect at a common point and form an angle of 90°. This angle is called a right angle. To represent that two

**straight**lines are

**perpendicular**to each other, we use the symbol ⊥.

## How do you make a perpendicular line?

To construct a **line perpendicular** to a **straight line** , simply click on **Perpendicular Line** and then click on the **straight line** and finally click on a point on the **straight line** or not belonging to it. In the figure below, the **line** s is **perpendicular** to the **line** r through a point A that does not belong to r.

## Which of the figures is formed by perpendicular lines?

To represent that two straight lines are **perpendicular** to each other, we use the symbol ⊥.

## What are non-perpendicular lines?

Parallel **lines ****are lines** in a plane that are always the same distance from each other. Parallel lines never intersect, while perpendicular **lines ****are** those that intersect at a right angle (90 degrees).

## What are perpendicular lines Brainly?

Response. **Perpendicular lines are lines** that intersect forming a right angle. **Perpendicular lines are** , therefore, a special case of concurrent **lines . In the scene below two competing ****straight lines** are represented .

## What are straight lines Brainly?

A **straight line ****is** nothing more than a line formed by points, they have no beginning or end, unlike semi-straight lines and **straight** segments .

## What are concurrent and parallel lines?

**Parallel lines** : two **lines are parallel** if they belong to the same plane (coplanar) and do not have a point of intersection or point in common. **Coincident lines** : they belong to the same plane and have all points in common. … **Concurrent lines** : two **competing lines** have only one common point.

## What are Coplanar and non-Coplanar lines?

**COPLANAR straight lines are straight lines** that lie in the same plane. … **NON-COPLANAR straight lines are straight lines** that are **not** in the same plane.
