Equate at least two pairs of components and solve for S or for t ;Obtain correct answer for s or for t(possible answers are -1,6,2/5for s and -3,4,-1/5for t);Verify that all three componen equations are not satisfied ;Show that the lines arenot parallel and arethus ...
Skew Lines Skew lines are lines that are neither parallel nor intersect each other. The distance between two skew lines is equal to the distance between their perpendiculars. If no parallel lines and no intersecting lines exist, the distance between them is zero. Two parallel lines that don’t...
This is a work on an application of octonions to Analytic Geometry. In the octonionic context, the orthogonal projection of a point onto a straight line is presented. Further, the best approximation pair of points of two skew lines over the octonions is studied....
Determine whether the lines L_1: x - 8 / 2 = y - 17 / 7 = z - 8 / 2 and L_2: x + 4 / 3 = y + 22 / 9 = z + 8 / 5 intersect, are skew, or are parallel. If they intersect, determine th...
Do non-parallel lines always intersect in 3D? No, two non-parallel lines in 3D space generally do not intersect. Such lines are called skew lines, and they do not lie in the same plane. In fact, two lines in 3D space can be: Intersecting at exactly one point; Parallel to each other...
To find the shortest distance between the two lines L1:x=k1,y=k2 and L2:x=k3,y=k4, we can follow these steps: Step 1: Represent the Lines in Vector FormThe first line L1 can be represented in vector form as:A1=k1^i+k2^j+0^kThis indicates that L1 is parallel to the z-axis...

i.e., the lines don't intersect. What is the Condition for the Intersection of Two Lines? A necessary condition for two lines to intersect is that they are in the same plane i.e., they are not skew lines. What are the Methods Used to Find Point of Intersection of Lines? The ...
