How to change polygon's points using JavaScript's DOM?

Question

Im coding another web design that has a triangle in it. Points "75 400, 275 300, 275 400".
Now I have to make it into points "80 500, 250 275, 250 300".

I tried making the code out of this, I read twice about the JavaScript Lessons, but when I tried it over 10 times, nothing happened. Even if I added setInterval() and window.onload in it.

How do I turn a polygon's shape into something?
