You can use the bounding box to resize and rotate your selection:
Drag the handles to make the selection larger or smaller. Drag a corner handle to adjust width and height simultaneously. Shift+drag a corner handle to size proportionally.
Position the cursor outside the bounding box to see the Rotate icon; drag when it appears to rotate the selection. Shift+drag to constrain to straight, 45-degree, or 90-degree angles.
Ctrl+drag (Windows) or Command+drag (Mac) a corner point to distort the selection.Distort, resize, and rotate a Photoshop selection with the Transform Selection feature.
Press Enter or Return or double-click in the center of the selection area to confirm the transformation; press Esc to release the transformation and return to the original selection.
