If you were looking for how to flip an object on Adobe Illustrator just like you would do on Adobe Photoshop it's come to the right place!
In Adobe Illustrator you would simply search for object - transform and then "reflect".
When using the reflect commands illustrator gives you the option to make a copy of the object that was selected and decide if you want to flip it vertically or horizontally.
