In order to mark out a 20-degree angle using a steel square, it is necessary to follow these instructions:
1. Ensure that the steel square is properly aligned and secured by placing it on a flat surface.
2. Identify the L-shaped corner of the steel square where the longer and shorter sides meet; this is the 90-degree angle.
3. Locate the 45-degree angle on the longer side of the square, usually marked close to the 90-degree angle.
4. Position the steel square with the 90-degree angle facing towards you in order to find the 20-degree angle.
5. Starting from the 45-degree angle, count towards the shorter side of the square, measuring a distance less than halfway between the 45-degree and 90-degree angles.
6. Mark a point on the shorter side of the square at this measured distance.
7. Align a straight edge or ruler with the marked point and the 90-degree angle on the square.
8. Draw a line connecting the marked point on the square and the straight edge/ruler, extending it beyond the square.
9. This line will create a 20-degree angle with the square, allowing you to accurately mark the desired angle on your workpiece.
Always remember to double-check your measurements and use a reliable protractor or angle gauge to ensure the accuracy of your marked angles.

6. At this measured distance, mark a point on the shorter side of the square.
7. Next, align a straight edge or ruler with this marked point and the 90-degree angle on the square.

To use a steel square to mark out 20-degree angles, you would first align one edge of the square with the reference line or edge. Then, you would locate the 20-degree mark on the scale of the square and draw a line along the other edge of the square, intersecting the reference line. This will create a 20-degree angle.
