What is a set square in technical drawing?
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.
How do you set a set square?
Step 1: Position an edge of the set square along the given line, AB. Step 2: Place a ruler against one of the other edges. Step 3: Slide the set square along the ruler until the edge used in Step 1 passes through the given point P. Step 4: Draw the line CD through P.
What is 60 degree set square?
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.
Why are set squares called set squares?
It could also be that the “set square” normally comes from a “geometry set” (a set of rulers/tools), so it is the “set square” the “square-making tool from the set”.

What are set squares used for in architecture?
Set square is a tool used in the technical drawings by architects and engineers to provide a planner angle to a predefined baseline. In simpler terms, it is used in drawing straight lines and angles.
What is at square used for?
T-shaped instrument known as a T square is used for establishing a horizontal reference on the drafting board. Most widely known are the T square, triangle, protractor, and compass; the parallel straightedge is an alternative to the T square.
