Answer Details
The tool shown in Fig 11 used to draw accurate right angles on card:
Set square [1] - a set square is a flat triangular tool (typically 45-degree or 30/60-degree) placed with one edge against a straight baseline. The adjacent edge then provides a precise 90-degree angle, allowing the designer to draw lines at exact right angles to the baseline. A try square or T-square would also produce accurate right angles and are accepted answers.
