# Quick Answer: What Happens When A Transversal Crosses Parallel Lines?

## What happens when a transversal intersects two parallel lines?

When a transversal intersects with two parallel lines eight angles are produced.

The eight angles will together form four pairs of corresponding angles.

All angles that are either exterior angles, interior angles, alternate angles or corresponding angles are all congruent..

## What are two parallel lines cut by a transversal?

If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent. If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent. If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.

## Do transversal lines have to be parallel?

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.

## How many Transversals can be drawn two lines?

Answer: The answer is infinite number of transversals. Step-by-step explanation: We are asked the question that how many transversals can be drawn for two distinct lines. A transversal is a straight line which cut both the lines at two distinct points.

## Are same side interior angles supplementary or congruent?

Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

## When a transversal crosses parallel lines alternate interior angles are congruent?

The alternate interior angles theorem states that, the alternate interior angles are congruent when the transversal intersects two parallel lines. Hence, it is proved.

## Can a transversal line be straight?

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

## How do you prove lines are parallel?

The first is if the corresponding angles, the angles that are on the same corner at each intersection, are equal, then the lines are parallel. The second is if the alternate interior angles, the angles that are on opposite sides of the transversal and inside the parallel lines, are equal, then the lines are parallel.

## Which angles are equal in parallel lines?

are equal in measure. If two parallel lines are cut by a transversal, the alternate interior angles are congruent. If two lines are cut by a transversal and the alternate interior angles are congruent, the lines are parallel.

## What pairs of angles are formed when two lines are cut by a transversal line?

When two lines are cut by a transversal, the pairs of angles on one side of the transversal and inside the two lines are called the consecutive interior angles . If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary .
