Does it say it's a square on the chart?if it does then yea, aspects don't have to be exact, they allow for orbs,
Quote from astro.com"There is also a certain amount of “play”, which means that an aspect is said to “work” or be operative within a few degrees either way of being exact. This margin of “play” is defined by the orbs. "
on astro it says the max orb on a square is 10° for the default settings,so at 80° you're reaching the maximum orb distance but it's still a square based on the information on the site.
