Technical Graphics  The Basics  AnglesIt is very important to be able to draw angles in Technical
Graphics. With your set squares sitting on your Tsquare you can
four commonly used angles. These are 30°, 45°, 60° and
90°. You can see these below.
These are the basic angles and are easy
to create using the set squares in the different orientations shown.
Always make sure that the Tsquare is flush with the side of the
drawing board and that the set squares are flush with the Tsquare.
