Q s regarding planetary and spirit invocation

[nox]

Hi.Im not sure if ill have to use the triangle when i wanna invoke planetary spirits an inteligences ,so i have a few questions about it.Any help is apreciated.
First i could use some advise regarding the corect preparation of the triangle for a certain ritual.I did some reading but it s not enough.I know that it has to be cosacrated but i don t know how.
I s it necesary to use the triangle when u invoke planerary intelegences or spirists?
Is it necesary to use the triangle when i m chargeing a talisman?or depends on the method u use to charge it .


thanks
