can somebody give me an example of a code to move a part around a right angle non stop?

Can somebody help me with a code that can move a part around a right angle non stop? I am new here and I can just move it till the end of the right angle. thank you!

Try this:

while wait() do
	part.CFrame *= CFrame.Angles(math.rad(90),0,0)
end

This is just an example, it's probably not what you're trying to do.
