What you learned: To resize layers

1. In the Layers panel, select one or more layers that contain images or objects you want to resize.
2. Choose Edit > Free Transform. A transform border appears around all the content on the selected layers. Hold the Shift key to avoid distorting the content, and drag the corners or edges until it is the desired size. Drag inside the transform border to move the content around the image. Drag outside the transform border to rotate the content.
3. Click the check mark in the options bar or press Enter (Windows) or Return (macOS) to finalize the change.
