Line of Intersection of Two Planes Calculator
Calculate the line of intersection between two planes using our interactive tool.
What is the Line of Intersection of Two Planes Calculator & How does it work?
The line of intersection of two planes in three-dimensional space can be found by solving a system of linear equations representing the planes. If the planes are not parallel, they intersect along a line. The direction vector of this line is perpendicular to the normal vectors of both planes.To find a point on the line, we can substitute one variable from the plane equations and solve for the other two. This gives us a parametric equation of the line.
vec{d} = vec{n}_1 times vec{n}_2
vec{d} = direction vector of the line, vec{n}_1 and vec{n}_2 are normal vectors of the planes.

Frequently Asked Questions
How do I find the line of intersection of two planes?
To find the line of intersection, input the equations of both planes into the calculator. It will provide you with the direction vector and a point on the line.
What is the direction vector of the line of intersection?
The direction vector of the line of intersection is perpendicular to the normal vectors of both planes. The calculator computes this using the cross product of the normal vectors.
How do I know if two planes are parallel?
Two planes are parallel if their normal vectors are scalar multiples of each other. If the calculator shows no intersection, the planes might be parallel.
Can this calculator handle non-parallel planes?
Yes, as long as the planes are not parallel and intersect in a line, the calculator can find their line of intersection.
What if I only have one plane’s equation?
The calculator requires two distinct plane equations to determine their line of intersection. You need both to proceed with the calculation.
How do I interpret the results from this calculator?
The calculator will give you a direction vector and a point on the line of intersection. Use these to write the parametric equations of the line.
Is there any limit to the complexity of plane equations?
The calculator can handle standard linear plane equations in three-dimensional space. Ensure your equations are in the form Ax + By + Cz = D for best results.
