Hi Gabriel,
Yes - this is possible - but it is a bit hard to find.
I will try to explain (and yes, this would need improvements in the
digitizing chapter of the QGIS manual).
Steps:
1. Enable Snapping on your active layer
2. Enable "Self Snapping"
3. Press the "Add Polygon Feature" button (but don't yet digitize)
4. Enable "Advanced Digitizing"
5. In the "Advanced Digitizing" panel select the angles you want to snap
to
6. Start digitizing by pressing the left mouse button and adding the
first segment with the second click
7. Add any additional segments by staying with the new segments within
the angle tolerance in order to get new segments with proper right
angles
8. If you want to close: first press "Alt-A" to fix the angle. Second:
go to your initial start point and snap to it with the Left Mouse Button
9. Press "Right Mouse button" to finish editing the polygon
Here is a Video demonstrating the steps:

don't have a radio voice ;-) )
As others have pointed out, you can uses the different "Add Rectangle"
modes in the "Shape Digitizing Toolbars", e.g. "Add Rectangle from 3
points".
Hope this helps,
Andreas

Hello,
I'm digitizing a square using the advanced digitizing tool, however
when I'm about to close the rectangle's last angle, the tool doesn't
offer me to see how to close it with a perfect square angle at the last
click. Thus cannot finish the figure as a perfect square (four 90
degree angles).
How can I perform the square with the 4 perfect 90 degree angles using
the digitizing tool?
Thanks a lot for your help.
Kind regards,
Gabriel
