Find intersection of 2 planes
How can I get the intersection line between two planes?
When two planes intersect, the vector product of their normal vectors equals the direction vector s of their line of intersection, N1 ´ N2 = s. To write the equation of a line of intersection of two planes we still need any point of that line.
Do two distinct intersecting lines determine a plane?
For example, given two distinct, intersecting lines, there is exactly one plane containing both lines. A plane is also determined by a line and any point that does not lie on the line. These characterizations arise naturally from the idea that a plane is determined by three points.
Do two planes always intersect in a line?
Two planes always intersect in a line as long as they are not parallel. Let the planes be specified in Hessian normal form, then the line of intersection must be perpendicular to both and , which means it is parallel to.
Can two planes only intersect at one point?
Two distinct lines intersect in more than one point. Through any two points, there is exactly one line. If two distinct lines intersect, then they intersect in exactly one point. If two distinct planes intersect, then they intersect in exactly one line.

Find the intersection of the two planes: Use a different method from that used in example 3. Solution Next we find a point on this line of intersection. Let z = 0 and solve the system of equations (3m 6 = 0 and x y — 5 = 0) —2 and y = 7 _ to get x So, the point (—2, 7, 0) lies on both planes and therefore it lies on the line of intersection.

2. Luckily we know how to do that now... Example: Find a vector equation of the line of intersections of the two planes x 1 5x 2 + 3x 3 = 11 and 3x 1 + 2x 2 2x 3 = 7. First we read o the normal vectors of the planes: the normal vector ~n 1 of x 1 5x 2 +3x 3 = 11 is 2 4 1 5 3 3 5, and the normal vector ~n 2 of 3x 1 +2x 2 2x 3 = 7 is 2 4 3 2 2 3 5.

The purpose of this last part of the lab is to get you to think about the intersection of geological structures (only simple planar layers) and topography. When working with geological maps, it is important to be able to tell something qualitatively about the dip of a planar feature or a planar layer from how it interacts with irregular topography.

To find the equation of the line of intersection between the two planes, we need a point on the line and a parallel vector. To find a point on the line, we can consider the case where the line touches the x-y plane, that is, where z = 0. If we take the two equations of the plane ‘ and substitute z = 0, we obtain the system of equations (1) (2)
