How do you add an angle in Photoshop?

To add an angle to a line or shape in Photoshop, you can use the Free Transform tool. Here's a step-by-step guide:

Draw a line or shape: Use the Line Tool (found under the Rectangle Tool) or any other shape tool to create the element you want to rotate. For the transform tool to work effectively on a line, ensure it's drawn as a path (e.g., using the Pen Tool to create a stroke). Alternatively, create a closed path and delete the extra segment later.
Select the layer: In the Layers panel, select the layer containing the line or shape.
Access Free Transform: Go to Edit > Free Transform (or press Ctrl+T on Windows or Cmd+T on macOS).
Enter the angle: In the options bar at the top, you'll see a field for rotation (usually represented by an angle symbol). Enter the desired angle in degrees. Positive values rotate clockwise, and negative values rotate counter-clockwise.
Commit the transformation: Press Enter (Return) or click the checkmark in the options bar to apply the transformation.

Important Considerations:

Paths vs. Shapes: Free Transform works well on both shape layers and path outlines.
Rotation Point: The object will rotate around its center point by default. You can move the center point before entering the rotation value to rotate the object around a different point. To move the rotation point, click and drag the small target icon that appears in the center of the transformed object.
Rasterized Layers: If your layer is a rasterized layer (not a shape or path), the transformation will cause some loss of quality if you scale up the layer. To avoid this, consider converting it to a smart object before transforming it (right-click on the layer in the Layers panel and choose "Convert to Smart Object").
Line Tool Note: If you are using the standard line tool, ensure the end caps are set to your liking before rotating, as this can influence the final appearance.
