Is it possible for two planes to meet in a point instead of in a line?
Ben Niehoff said:I have to disagree with HallsofIvy. The answer depends on the dimension of the ambient space in which the planes live.
In 3 dimensions, Halls is correct.
In 4 dimensions and higher, two planes (i.e., 2-dimensional objects) can certainly intersect in a point.
The intersection of two planes is the line where the two planes meet or cross each other.
To determine if two planes intersect, you can solve the equations of the two planes simultaneously. If the solution results in a consistent system of equations, then the planes intersect. If the solution is inconsistent, then the planes are parallel and do not intersect.
No, two planes can only intersect at one point. This is because planes are two-dimensional and do not have depth or thickness, so they cannot overlap or intersect at multiple points.
If the equations of two planes are the same, then they are essentially the same plane and will coincide with each other. This means that they will intersect at every point and there are an infinite number of points of intersection.
If two planes are parallel, they will never intersect. If two planes are perpendicular, they will intersect at a single point. If two planes are neither parallel nor perpendicular, they will intersect at a line.
