Is there a way to get the position left of a part with the angle?

Okay so, I have a game, and there is a tween and when I tween it, some of the parts have an angle at 40 degrees or like 90 degrees. So my question is, how would I get the position to the left of the part with the angle, like, the part will move left with or without a different angle but, I am trying to get the part to move left of what the angle is at.

Part 1's angle is at 60 degrees, I move the part up a few studs and left a few studs

Part 2's angle is at 90 degrees, I move the part up a few studs

Although, I do not know the angle which makes this even trickier.

what I have tried doing is, sobbing and crying. Which wasn't helpful.

local part = workspace.Part
part.Position = part.Orientation.Magnitude * part.Position.Magnitude
-- ok i do not know the rest

If someone knows how to fix this, please tell me, I would greatly appreciate some code or some math, thanks.
