You can get small machinist squares for layout at many industrial and tool
stores. I bought mine at Enco. The small ones are perfect for checking
the
accuracy of saw setups.

It's a trifle pricy, but I was thinking of buying one of the digital "tilt
boxes" for measuring my blade angle. It would be convenient on those angle
cuts. Of course, if all I was cutting was 90° and 45° cuts then it would be
cheaper and easier to pick up a 45° square.
