What else can I help you with?
Lines that have one point in common?
Intersecting lines. If they have only one point in common, then they are also non-parallel.
What do parallel lines have?
No point in common. That is correct. More common explanation is that even if you extend the lines in either direction, they would not touch (i.e. have a common point.)
Is a line parallel to itself?
Two lines are not parallel if they have exactly one point in common; otherwise they are parallel. So this means a line is parallel to itself!
What is a point on the horizon where parallel lines appear to meet?
A point on the horizon where parallel lines appear to meet is called the vanishing point.
How did Euclid come up with parallel lines?
Euclid introduced the concept of parallel lines in his work "Elements," where he defined parallel lines as lines in the same plane that do not intersect, regardless of how far they are extended. His systematic approach to geometry involved postulating basic axioms, one of which states that through a point not on a line, there is exactly one line parallel to the given line. This foundational idea laid the groundwork for Euclidean geometry and influenced subsequent mathematical thought on the nature of space and lines.
Lines that have no point in common?
parallel
Lines that have one point in common?
Intersecting lines. If they have only one point in common, then they are also non-parallel.
Two coplanar lines with no point in common are?
parallel
What do parallel lines have?
No point in common. That is correct. More common explanation is that even if you extend the lines in either direction, they would not touch (i.e. have a common point.)
Are 2 lines have no common point is always parallel?
In a 2 dimensional plain they would have to be parallel in order to have no common point; in a 3 dimensional field they do not have to be parallel.
What would happen if parallel lines weren't parallel?
They would 'intersect'. ('cross', have one point in common)
Is a line parallel to itself?
Two lines are not parallel if they have exactly one point in common; otherwise they are parallel. So this means a line is parallel to itself!
Lines with one point in common?
Two lines with one point in common are said to intersect at that point. Any two straight lines with infinite length will eventually intersect each other, unless they are parallel to each other.
What are lines that have one point in common?
Lines that have one point in common are said to intersect one another at that point. Almost all straight lines of infinite length intersect one another, unless they are parallel to each other.
How many points do intersecting lines have in common?
Intersecting lines have exactly one point in common, which is the point of intersection. At this point, the two lines cross each other. If lines are parallel, they do not intersect and have no points in common. Lines that are coincident lie on top of each other and share infinitely many points.
What is the common point at which two lines meet?
point I believe the word you're looking for is "intersection". Two non-parallel lines that lie in the same plane will have one point in common where they cross, and that point is the intersection.
Which pair of undefined terms is used to define the term parallel lines?
The pair of undefined terms used to define parallel lines is "line" and "point." Parallel lines are defined as two lines in a plane that do not intersect, regardless of how far they are extended, and a point is used to describe the position relative to these lines. These terms are foundational in geometry, serving as the basis for more complex definitions and theorems.
