## Can intersecting lines be parallel?

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

## When can two lines become parallel?

Note that two lines are parallel if their slopes are equal and they have different y-intercepts. In other words, perpendicular slopes are negative reciprocals of each other.

**Which two lines are equidistant and will never meet?**

Parallel lines are equidistant lines (lines having equal distance from each other) that will never meet.

### Are parallel lines an empty set?

A set that does not contain any element is known as an empty set or a null or a void set . It is an empty set as parallel lines do not have a common point. It is not a non – empty set .

### What happens if two lines are parallel?

Two lines are parallel lines if they do not intersect. The slopes of the lines are the same.

**How many solutions do parallel lines have?**

Parallel lines do not ever cross. So there’s zero solutions.

#### Which situation shows parallel lines?

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.

#### Are parallel lines equal?

In other words, two lines are parallel when the interior angles on the same side sum to exactly 180 degrees. The angles that fall on alternate sides of a transversal and between the parallels (called alternate angles) are equal.

**Why is a point common to any two parallel lines?**

(iv) { y : y is a point common to any two parallel lines} Parallel lines do not intersect so they do not have any common point. Hence, it is a null set.

## Is every line is parallel to itself?

Parallel lines are lines in a plane which do not intersect. According to the axioms of Euclidean geometry, a line is not parallel to itself, since it intersects itself infinitely often. …

## How do you know if two lines segments are parallel?

Parallel Line Segments: A line segment is a line with two endpoints. Two line segments are said to be parallel if they would never intersect if we were to extend them forever past both their endpoints.

**Which statement is true if two lines are parallel?**

Two lines are parallel if and only if they have the same slope. The slope of one of the lines is . The slope of the other is , so the lines have the same slope. The lines are parallel.

### Can two perpendicular lines intersect at exactly one point?

*** Two lines are said to be perpendicular if they intersect at right angles. Any two perpendicular lines intersect at exactly one point. User: A rectangle has a length of 10 ft. and a width of 6 ft.

### Will two non parallel lines always intersect?

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.

**Can two different planes intersect a line?**

Two distinct planes are either parallel or they intersect in a line . A line is either parallel to a plane, intersects it at a single point, or is contained in the plane. Two distinct lines perpendicular to the same plane must be parallel to each other.

#### Can two lines intersect at only one point?

In Euclidean geometry two lines can intersect at only one point. In another Geometry, however, two lines may intersect at two points (think surface of a ball). The intersecting line postulate may be equivalent to the number of degrees in a triangle.
