How to implement this?

Create a vector object and put there picture, draw angle. If photoshop older, just draw a vector object and using masks cut out a similar shape from the picture.

UPD: For example:
1. Shape, top to insert an image prntscr.com/jcxgrj
2. The figure should be under the layer with the picture, click on the picture, right-click -> create clipping mask prntscr.com/jcxh7o
3. The result: prntscr.com/jcxhd4
