Fig. 2 paper and slide the other along its edge. Geometrical draw-ing can be greatly facilitated by the proper use of set-squares,so it is advisable to practise their use. GENERAL DIRECTIONS When a problem contains many arcs of circles, it is advis-able to connect the arc with its corresponding… … In drawing intersecting arcs for bisecting lines, etc., thearcs should not intersect each other too obtusely or tooacutely: the nearer the angle between the arcs approaches90 the easier it will be to ascertain the exact point required. In joining two points by a line, first place the point of…
