To mark out 75-degree angles using a steel square, the following steps are typically followed:
1. Ensure that the long side of the square is parallel to the edge where the angle will be marked, and place it on a flat surface or workpiece.
2. Align one edge of the square with the desired starting point of the angle, which will serve as the reference line for marking.
3. Locate the line on the steel square that represents a 45-degree angle, usually marked with a number or symbol.
4. Starting from the reference line, count inwards along the 45-degree angle line in the direction of the desired angle. In this case, measure 30 degrees inward along the 45-degree line.
5. Once the appropriate distance is measured, make a mark at that point, indicating the starting point of the 75-degree angle.
6. From the starting point, measure an additional 75 degrees in the desired direction, using the appropriate scale on the steel square. This can be the 90-degree line or a specific angle scale marked on the square.
7. Make a second mark at the endpoint of the 75-degree angle, completing the marking process.
Remember to verify your measurements and use a sharp pencil or marker for accurate and visible markings. It is also advisable to practice using the steel square on scrap material before marking the final workpiece to ensure precision.

Remember to double-check your measurements and use a sharp pencil or marker to ensure accurate and visible markings. Additionally, practice using the steel square on scrap material before marking your final workpiece to ensure precision.
To use a steel square to mark out 75-degree angles, you would typically align the 45-degree angle of the square with the edge of the material. Then, using a protractor or angle finder, measure 30 degrees from the square's 45-degree angle, which will give you a total of 75 degrees. Finally, draw a line along the edge of the square to mark out the 75-degree angle.
