Pocket Square or Right Angle

Basic right angle guide/ruler/marker. Can't find my combination square anywhere! Hmmm, do I even own one?.... I made this to mark wood before cutting and to see if my glue jobs are square, fits in my work apron pocket. It's a basic right angle, please use your angle responsibly :-)

Beveled side is 5.5 cm, non beveled side is 5.0 cm, width is 15mm.
