How to automatically align an object strictly vertically about its axis in Adobe Illustrator?

Question

Adobe Illustrator

Using the example of a simple rectangle, you have to slowly rotate it until there is a value of 0 °
When there are several such objects, then for a long time, sit and move the mouse, tried to hold down the rotation operation, and press 0 on the Num keyboard, I thought it would help, but it didn’t help

Answer 1

Good day.
In the upper menu "window" -> "transform", a panel will open, in it the rotation value can be set to 0.
