Question

is the following statement true or false? the intersection of three planes can be a point. true false

Explanation:

Three planes can intersect at a single unique point when their normal vectors are linearly independent, meaning no plane is parallel to the others and they do not all intersect along a common line. An example is the coordinate planes \(xy\)-plane, \(yz\)-plane, and \(xz\)-plane, which intersect only at the origin \((0,0,0)\).

Answer:

true
