In three-dimensional space, a first degree equation in the variables x, y, and z defines a plane, so two such equations, provided the planes they give rise to are not parallel, define a line which is the intersection of the planes. Its roof, sides and floor are parts of seven different planes, which are referred to in the questions below. The planes will then form a triangular "tube" and pairwise will intersect at three lines. Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website! The two planes on opposite sides of a cube are parallel to one another. In the case where the electric field at every point on two intersecting equipotential surfaces is zero, both of those equipotential surfaces are considered a single equipotential surface rather than two, since the potential at all the points on both the surfaces is the same. What is the conflict of the short story sinigang by marby villaceran? Three planes may all intersect each other at exactly one point. See Emilio's answer to a similar question for how to think about intersecting surfaces formally. yes; it is possible. The intersection of three planes is either a point, a line, or there is no intersection if any two of the planes are parallel to each other. 3 Planes in 3-Space Now consider three planes in R 3.If we pick two of these planes, we generically expect them to intersect in a line. Two planes that do not intersect are said to be parallel. I'm staring. The second and third planes are coincident and the first is cuting them, therefore the three planes intersect in a line. Write.
