Atoms in the same plane

How do you know when atoms will be in the same plane? And do double or triple bonds determine if atoms will be in the same plane since a molecule can't bend if it has double or triple bonds?

I'm pretty sure that to determine whether or not atoms are in the same plane you have to see if there is the presence of a pi bond, which results from either a double or triple bond between atoms. Otherwise, if there is just a single bond/sigma bond, the atoms are free to rotate.

Also, if the structure contains trigonal planar or linear arrangement, the atoms involved will be in the same plane.

Even if the molecule is "bent" or "angular" the molecule as a whole should be found in a single plane. This is true for those "bent" shaped molecules, but also for molecules that are trigonal "planar" and square "planar" (the name suggests that they lie in such a plane).

Atoms will be in the same plane if they have a double or triple bond since they can't rotate due to having a pi bond. Furthermore, if they are either trigonal or square planar the atoms also lie in the same plane.
