What Is a Set Square Used For? Set squares are used for drawing perpendicular and parallel lines, according to Mathsteacher.com. The two set squares are named according to their angles.


A set square or triangle (American English) is an object used in engineering and technical drawing, with the aim of providing a straightedge at a right angle or other particular planar angle to a baseline.. The simplest form of set square is a triangular piece of transparent plastic (or formerly of polished wood) with the centre removed. More commonly the set square bears the markings of a ...


A set square is a drawing aid used to draw known, pre-set angles in technical drawing and mathematical exercises. Set squares are triangular in shape and typically made of thin plastic, wood, or, less commonly, light-gauge steel. All set squares offer three drawing surfaces or planes representing three different angles which always include one ...


Use a set square to draw a perpendicular to a given line, AB, through a point, P, not on the line. Solution: Step 1: Set an edge of the set square on the given line so that the other edge is just in contact with the point.


This can be used for drawing vertical lines. The 30/60 degree set square also has a 90 degree angle. This set square can be used to draw 30, 60 or 90 degrees angles. Set squares are only accurate if they are used along with a T-square. The set square must rest on the T-square which should be pushed against the edge of the board.

Set squares are useful for drawing parallel lines and perpendicular lines.


A T-square is a technical drawing instrument used primarily as a guide for drawing horizontal lines on a drafting table.It may also guide a set square to draw vertical or diagonal lines. Its name comes from its resemblance to the letter T. T-squares come in varying sizes, common lengths being 18 inches (460 mm), 24 inches (610 mm), 30 inches (760 mm), 36 inches (910 mm) and 42 inches (1,100 mm).


You can only rely on your tablesaw's 0° and 45° blade stops if you've set them accurately to begin with. Use your combo square to set each angle precisely, adjusting the 0° stop before moving to the 45° stop. Place your square's head on the cast-iron top, as shown, rather than the throat insert for maximum accuracy.


Set Squares are used for several purposes. It totally depends what your requirement is. For example, they can be used for Geometry if you are a geometry fan. But this is just basics. Else, there is a subject, popularly known as Technical Drawing, ...
