Each airplane cuts the other two in a line Two Coincident Planes and the other Intersecting castle in a Line

You are watching: Three planes that intersect in one line

How to find the relationship between two planes.

Given 3 planes:

case 2.1. Each plane Cuts the various other Two in a line r=2 and also r"=3

The 3 planes form a prismatic surface

Case 2.2. Two Parallel Planes and also The various other Cuts each in a heat r=2 and r"=3 2 rows the the coefficient matrix room proportional:

Case 3.1. 3 Planes Intersecting in a line r=2 and r"=2

Case 3.2. 2 Coincident Planes and also the various other Intersecting them in a Line r=2 and r"=2 2 rows of the augmented matrix room proportional:

Case 4.1. Three Parallel Planes r=1 and also r"=2

Case 4.2. Two Coincident Planes and also the other Parallel r=1 and also r"=2 2 rows that the augmented matrix room proportional:

Case 5. Three Coincident Planes r=1 and also r"=1

State the relationship in between the three planes:

: -2x+6y+z=-6 ,
: -x-y+z=9 and
: x+2y=-2 are:
