When two lines intersect they intersect in one and only one?
Point.
When two lines intersect do they intersect in different ponts?
No, two straight lines can intersect at only one point and that is their point of intersection.
Do perpendicular lines intersect in at least two points?
Perpendicular lines intersect at one point only.
Do two lines always intersect at one point?
If two different lines intersect, they will always intersect at one point.
Two lines intersect in more than one point?
In Euclidean plane geometry two infinitely long straight lines intersect at only one point
Can two straight lines intersect at only one point?
yes
Does intersecting lines meet at two points?
Lines in a plane can intersect at only one point.
Can three lines intersect in only one point?
Any number of lines can intersect all at the same point. Think of a circle. Now think of all of its diameters.
Two lines only intersect at exactly one point?
Two straight lines, whether they're in the same or different planes, must intersect at either one point or else at no points.
How many solutions will a system of equations have if the graphs of the lines intersect?
A system of equations will have one solution if the graphs of the lines intersect. This is because the lines intersect at a single point. Let's say that point is (a, b). The x = a, y = b is the one and only solution for the system.
Parallel lines are defined as lines that have only one point in common?
No, parallel lines never intersect, so they do not have any points in common. Intersecting lines have one common point.
When two or more lines intersect at a point they are said to be?
Theorem: If two lines intersect, then exactly one plane contains both lines. So, when two or more lines intersect at one point, they lie exactly in the same plane. When two or more lines intersect at one point, their point of intersection satisfies all equations of those lines. In other words, the equations of these lines have the same solution, which is the point of intersection.
