Example: Find the intersection point and the angle between the planes: 4x + z − 2 = 0 and the line given in parametric form: x =− 1 − 2t y = 5 z = 1 + t Solution: Because the intersection point is common to the line and plane we can substitute the line parametric points into the plane equation to get: (x, y) gives us the point of intersection. The routine finds the intersection between two lines, two planes, a line and a plane, a line and a sphere, or three planes. is a point on the line and ???v??? Find out what you can do. parallel to the line of intersection of the two planes. You can calculate the length of a direction vector, and you can calculate the angle between 2 direction vectors (at least in 2D), but you cannot calculate their intersection point just because there is no concept like a position when looking at direction vectors. SEE: Plane-Plane Intersection. However, none of those equations had three variables in them and were really extensions of graphs that we could look at in two dimensions. Remember, since the direction number for ???x??? Geometry. As long as the planes are not parallel, they should intersect in a line. The following matrix represents our two lines: $\begin{bmatrix}2 & -1 & -4 & -2 \\ -3& 2 & -1 & -2 \end{bmatrix}$. Note that this will result in a system with parameters from which we can determine parametric equations from. Calculation of Angle Between Two plane in the Cartesian Plane. Viewed 1k times 2.
