k so you can probably what, like, angle the sails differently for direction changes? but what if the wind is blowing in the exact opposite direction

Because ships have keels, you can choose your direction of movement up to ~100° either side of the wind. If you want to exceed that, you tack.

Finally something on Twitter I actually know something about! And I have pictures! This is for a fore-and-aft rigged ship, where the sails are mainly along the centerline of the ship and can be hauled to either side, pivoting away from the mast.pic.twitter.com/4IHVbcnMZV

A full-rig or ship-rig, what you think of when you imagine naval battles and such, with three masts and multiple sails, has different limitations and generally can't sail as close (into) the wind as a fore-and-aft.

Every sail plan on every ship design has different sailing qualities and a different point on the winds from which it sails best. The designers were really quite brilliant for the tools they had at hand.
