Place one end of the measuring tape or ruler at one end of the angle and extend it to the opposite end. Ensure that the measuring tape is straight and aligned with the edge of the angle. Read the measurement in inches or millimeters to determine the length. 3. Next, measure the width or thickness of the angle. Place the measuring tape or ruler perpendicular to the length of the angle, and measure the distance between the two parallel sides. This will provide you with the width measurement. 4. To measure the height or depth of the angle, place the measuring tape or ruler perpendicular to the width measurement. Again, ensure that the measuring tape is aligned with the edge of the angle and measure the distance between the two sides. This will provide you with the height measurement. 5. To ensure that the angle is accurately 90 degrees, use a square. Place the square against one side of the angle and ensure that it is aligned with the adjacent side. Check if the corner of the angle fits perfectly within the square. If it does, the angle is indeed 90 degrees. If not, it may be necessary to adjust or correct the angle. 6. Lastly, if you need to measure the angle of the steel angle, you can use a protractor. Align one side of the protractor with one side of the steel angle and see where the other side intersects with the protractor scale. Read the angle measurement to determine the exact angle. By following these steps and using the appropriate tools, you can effectively inspect and measure the dimensions of a steel angle.
