The handles centered on the line of the box will stretch the object, list those two

1) Horizontal handles: These handles are located on the left and right sides of the object. When dragged horizontally, these handles stretch or compress the object along its width, making it wider or narrower.

2) Vertical handles: These handles are located on the top and bottom sides of the object. When dragged vertically, these handles stretch or compress the object along its height, making it taller or shorter.

The handles are centered on the line of the box

Apologies for the confusion. If the handles are centered on the line of the box, there would generally be four handles present:

1) Horizontal handles: These handles are located on the left and right sides of the object and aligned exactly on the centerline of the box. Dragging them horizontally will stretch or compress the object equally on both sides.

2) Vertical handles: These handles are located on the top and bottom sides of the object and aligned exactly on the centerline of the box. Dragging them vertically will stretch or compress the object equally on both top and bottom sides.

Name it

In this case, the handles can be referred to as:

1) Centered horizontal handles
2) Centered vertical handles
