They have an infinite number of solutions.
the parallel lines never intercept so they do not have any common points.
No, parallel lines never intersect, so they do not have any points in common. Intersecting lines have one common point.
If two lines cross they share a point of intersection. For two straight lines this is limited to one common point, for two circles two points and for complex lines like two sine waves the number of common points has no limit.
Parallel lines lying in a plane do not intersect each other. They share exactly zero points in common.
Zero. A null angle is formed by two straight lines that coincide.
one solution
They are four lines that coincide pairwise in at least four distinct points.
When a system of linear equations is graphed, each equation represents a line in a coordinate plane. The solutions to each equation correspond to the points on that line. The intersection points of the lines represent the solutions to the system as a whole, indicating where the equations are satisfied simultaneously. If the lines intersect at a single point, there is a unique solution; if they are parallel, there are no solutions; and if they coincide, there are infinitely many solutions.
If the lines intersect, then the intersection point is the solution of the system. If the lines coincide, then there are infinite number of the solutions for the system. If the lines are parallel, there is no solution for the system.
the parallel lines never intercept so they do not have any common points.
When two lines intersect, the system of equations has exactly one solution. This solution corresponds to the point of intersection, where both equations are satisfied simultaneously. If the lines are parallel, there would be no solutions, and if they coincide, there would be infinitely many solutions.
one solution; the lines that represent the equations intersect an infinite number of solution; the lines coincide, or no solution; the lines are parallel
If the two lines are actually "on top of each other", they can have infinitely many points in common. If they are parallel, they have no points in common. If they are perpendicular, they have one point in common.
If there are no common points but both lines lie n the same plane they are considered "coplanar points"
Three noncollinear points ( A ), ( B ), and ( C ) determine exactly three lines: line ( AB ), line ( BC ), and line ( AC ). Each pair of points defines a unique line, and since the points are noncollinear, no two lines coincide. Thus, the total number of lines determined by points ( A ), ( B ), and ( C ) is three.
Parallel lines or skew lines
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.
