In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points. Transversals play a role in establishing whether two other lines in the Euclidean plane are parallel.

**Definition**: A **line** that cuts across two or more (usually parallel) **lines**. In the figure below, the **line** AB is a **transversal**. It cuts across the parallel **lines** PQ and RS. If it crosses the parallel **lines** at right angles it is called a perpendicular **transversal**.

Additionally, what are the angles formed by a transversal line? When two **lines** are cut by a **transversal**, the pairs of **angles** on either side of the **transversal** and inside the two **lines** are called the alternate interior **angles** . If two parallel **lines** are cut by a **transversal**, then the alternate interior **angles formed** are congruent .

Moreover, what is an example of transversal?

A **Transversal** is a line that crosses at least two other lines. The red line is the **transversal** in each **example**: **Transversal** crossing two lines. this **Transversal** crosses two parallel lines.

What does a transversal equal?

Two angles **are** said to be supplementary when the sum of the two angles **is** 180°. When a **transversal** intersects with two parallel lines eight angles **are** produced. The eight angles **will** together form four pairs of corresponding angles.

### What is a perpendicular line?

In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). A line is said to be perpendicular to another line if the two lines intersect at a right angle.

### How do you find the measure of an angle?

Using a Protractor The best way to measure an angle is to use a protractor. To do this, you’ll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle’s measurement to the nearest degree.

### Can there be two Transversals?

When a parallel-lines-with-transversal drawing contains more than three lines, identifying congruent and supplementary angles can be kind of challenging. With the above figure, you can use lines a, b, and c, or you can use lines a, b, and d, but you can’t use both transversals c and d at the same time.

### What does it mean to be congruent?

Congruent. Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length.

### What is the definition of parallel lines?

Parallel lines are two lines that are always the same distance apart and never touch. In order for two lines to be parallel, they must be drawn in the same plane, a perfectly flat surface like a wall or sheet of paper. Any line that has the same slope as the original will never intersect with it.

### What is the meaning of bisector?

A bisector is something that cuts an object into two equal parts. It is applied to angles and line segments. In verb form, we say that it bisects the other object.

### Are parallel lines congruent?

If two parallel lines are cut by a transversal, the corresponding angles are congruent. If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel. Interior Angles on the Same Side of the Transversal: The name is a description of the “location” of the these angles.

### What are the names of angles on parallel lines?

At each of the parallel lines adjacent angles are supplementary. The angles have special names identifying their positions with respect to the parallel lines and transversal. They are corresponding angles, alternate interior angles, or alternate exterior angles. An angles is congruent to its matched angle.

### Can a transversal be perpendicular?

The transversal line can intersect the parallel lines at any angle. When the angle of intersection is a right angle (90°), the transversal line is called a “perpendicular transversal”, and we will now show that if it is perpendicular to one line, it is also perpendicular to the other parallel line.

### What are the properties of transversal?

First, if a transversal intersects two lines so that corresponding angles are congruent, then the lines are parallel. Second, if a transversal intersects two lines so that interior angles on the same side of the transversal are supplementary, then the lines are parallel.

### What does transversal mean in business?

Transversal may refer to: Transversal (geometry), a line that intersects two or more lines at different points. Transversal (instrument making), a technique for subdividing graduations. Transversal Corporation, a software company.
