Yes, a steel square can be used for checking the squareness of picture frames. A steel square, also known as a framing square or carpenter's square, is a versatile tool commonly used in woodworking and construction. Its 90-degree angle and straight edges make it ideal for measuring and checking right angles. When using a steel square to check the squareness of a picture frame, you can place it against the corners of the frame to ensure they are perfectly perpendicular. By aligning the edges of the square with the frame corners, any discrepancies in squareness can be easily identified and corrected. Therefore, a steel square is a reliable tool for ensuring that picture frames are properly squared.
