The Line of Intersection Between Two Planes. 1. Find the directional vector by taking the cross product of n → α and n → β, such that r → l = n → α × n → β. If the directional vector is (0, 0, 0), that means the two planes are parallel. Then they won’t have a line of intersection, and you do not have to do any more calculations.
2x + 3y − 2z + 2 = 0. To calculate an intersection, by definition you must set the equations equal to each other such that the solution will provide the intersection. In short, set x + 2y + z − 1 = 2x + 3y − 2z + 2 = 0 To get a matrix you must solve. I found another solution.
Aug 18, 2023 · However, if two planes are parallel and distinct, they won’t intersect. If they are coincident (i.e., the same plane), then their intersection is the plane itself. Finding the Intersection of Two Planes. Determine the Direction Vector of the Line of Intersection. Begin by identifying the normal vectors of the two planes.
The solution is the set of all points in either plane Note: If P2 (5, —1, 0) did not lie on m, the planes would have been parallel and distinct In this case, there would be no intersection between the two planes. Examples Example 1 Determine the intersection of the two planes: : 3m — 2y 4z — (5, Solution A normal vector of is

Aug 17, 2024 · When two planes are parallel, their normal vectors are parallel. When two planes intersect, the intersection is a line (Figure \(\PageIndex{9}\)). Figure \(\PageIndex{9}\): The intersection of two nonparallel planes is always a line. We can use the equations of the two planes to find parametric equations for the line of intersection.
Jan 18, 2024 · The parametric equation of the line of intersection of two planes is an equation in the form r = (k1n1 + k2n2) + λ (n1 × n2). where: n1 and n2 — Normalized normal vectors. k1 and k2 — Coefficients of the equation in the form ki = di - dj(n1 · n2)/ (1 - (n1 · n2)) where d is the constant of the plane equation.
