State three uses of set Square in the technical drawing?

1. To draw perpendicular lines: A set square can be used to ensure that lines are drawn at perfect right angles to each other, which is essential for creating accurate technical drawings.

2. To measure and transfer angles: Set squares can be used to measure and transfer angles from one part of a drawing to another, ensuring that all angles are consistent and precise.

3. To create parallel lines: Set squares can be used to create parallel lines by aligning the edge of the square with an existing line and drawing along the edge of the square. This is useful for creating symmetrical and uniform designs in technical drawings.

1. Drawing parallel lines: A set square can be used to draw parallel lines at any angle by placing its edge along the existing line and sliding it to the desired position.

2. Drawing perpendicular lines: A set square can be used to draw perpendicular lines by placing its right angle corner at the point where the lines intersect.

3. Measuring and transferring angles: A set square can be used to measure and transfer angles by placing its edge along one side of the angle and marking the other side on the paper.
