Jagged diagonal lines in triangle shape

Hey all! I'm working with some triangles within a Christmas tree graphic (created with the polygon tool) that have pretty jagged diagonal edges. Is there a way to fix this? It shows up in the vector file as well as when I export it as a PNG or PDF , so I'm wondering if it's something I'm doing. I have anti-aliasing checked, and tried turning the GPU preview on and off and none of that helped. You can see that it's more pronounced in the two, larger blue triangles than in the smaller green ones.

I redrew the triangles and that didn't change anything...I tried changing the width and height dimensions instead of dragging to resize. I even tried using the smooth tool but that didn't seem to change anything. Is there anything else I can do? I'm kind of in a bind because I need to share this file with other people by end of day...I'm not sure if there's anything I can fix or this is just how diagonal lines go, but any insight would be highly appreciated. Thank you!

Since nobody who has commented here can see the jagged edges you see, it may be something on your side.

Did you check your Illustrator Preferences to see if Anti-aliased Artwork is checked?

Is the contrast of you monitor set too high?

Did you check your work on another computer?

I found an article online on how to master pixel perfect icons.

Like Eric_Dumas mentioned

pixel preview on:

pixel preview off:

Can you confirm that?

Thanks for taking a look! The one that's looking most pixelated to me is the navy blue tree. I see a little bit of it on the turquoise one, and not at all in the green one. Is that just on my end?

I am using the latest version of Illustrator, updated 9 days ago, and right now I am accessing it on Windows 10. I double-checked and I don't have pixel preview turned on.

Your monitor has pixels, so what do you expect? In the end certain edges cannot be straight.

Will this be printed? Or will it be online? Presented on a projector?

Hi,Can you confirm the version of the software and the operating system you are using?

Did you have any rasterising settings turned on? including the web pixel preview?

I don't see the problem when I look at the file, of at an exported PNG.
Now, if I zoom in to 2800%, then it shows in the PNG, but that is to be expected in a raster file, and it should no be being viewed at that size anyway.

Even at 6400%, I don't see it in the AI file.

Same results for me.
