Squares

Overview

A square is a specialist tool used in design and technology for measuring and marking out right angles and straight lines.
It takes its name from its traditional shape, although modern squares come in a range of designs with various features.
The tool typically consists of a straight edge at a right angle to another straight edge.

A set square or triangle square is used for drawing precise angles, often 45 degrees or 90 degrees.
Adjustable squares have a moveable blade that can be locked in place at any angle between 0 and 180 degrees.
A combination square has multiple parts and can be used to achieve a variety of measurements and angles.
The try square is used to test the accuracy of a right angle, commonly in woodworking.

Squares are fundamental tools in the field of technical drawing, allowing engineers and architects to make precise plans and diagrams.
In construction and carpentry, squares are used for marking out straight cuts to ensure components fit together accurately.
Squares are used in metalwork and fabrication for checking the squareness of a piece and marking out precision components.

Accuracy: A square must be true to ensure accuracy in the final product. It’s important to regularly check a square’s accuracy and recalibrate it when necessary.
Material: The material of the square is crucial, High-quality squares are usually made of hard-wearing materials, like steel or aluminium, which resist wear and distortion.
Size: Squares come in many sizes depending on the work being undertaken. Larger squares are ideal for marking out larger pieces, whereas smaller ones are better for finer detailed work.
Maintaining Your Square: Regular cleaning and protection from rust or damage helps to prolong the life and maintain the accuracy of a square.
Safety: When using a square for marking out, secure the workpiece to prevent it from moving and causing inaccuracies or safety risks.
