You are looking for the word

OPERATORS!

Explanation: Let's take the image of X's:

Overlay the provided shapes:

Identify any X's that are NOT corners (non-corny), that is, they are not under a corner of any shape:

Then let's play "connect the dots" in each of the 4 shapes:

And we have just drawn the
