Point of intersection of two lines in 3d. A point px y z is on the line l if and only if the direction numbers determined by p 0 and p 1 are proportional to those determined by p 1 and p 2. Bear in mind that there will be one of the following outcomes. Point of intersection is 4 0 1 x 13 y 1 1 z 1 0 lamda x 42 y 0 0 z1 3 alfa if two lines intersect at these points these cordinates are ssme. Distance between two points.
In three dimensional euclidean geometry if two lines are not in the same plane they are called skew lines and have no point of intersection. Ill show how to solve this problem using an example using the vector based form of a two straight lines. If one knows a specific line in one plane for example two points in the plane and this line intersects the other plane then its point of intersection i will lie in both planes. If you equate z and.
Vecr1 52 1 lamda1 2 3 l2. Infinitely many solutions if the lines coincide. This is the closest the lines get to each other. Vecr2 2.
As i mentioned earlier one can find the two points on the respective lines that are closest and these turn out to be 296792584 on line ba and 216768616 on dc. If the proportionality constant is t we see that the conditions are. Line passing through two points. P s i s n1 x n2.
In other words your lines do not intersect in three dimensional space.
