Which tool in Adobe Animate allows you to resize and flip objects?

The tool that allows you to resize and flip objects in Adobe Animate is the Transformation tool. This versatile tool provides various functions for altering the properties of selected objects, including scaling, rotating, and flipping them along either the horizontal or vertical axis. By using the Transformation tool, you can easily manipulate the size of objects to fit your design needs, without having to create new objects or manually adjust their dimensions.

In contrast, other options focus on different functionalities. The Stamp tool is typically used for duplicating shapes or objects within the animation, while the Alignment tool is designed to facilitate the arrangement and positioning of objects relative to one another, rather than modifying their size or orientation. The Mask tool is used for creating visibility effects by hiding or revealing portions of layers beneath it, which does not involve resizing or flipping objects. Thus, the Transformation tool stands out as the appropriate choice for resizing and flipping tasks in Adobe Animate.
