PRIN. OF DRAFTING AND SHOP DRAWINGS - OD1641 - LESSON 1/TASK 2
Draw a line through point 3 perpendicular to line 1-2 which intersects
line 1-2 (view D).
Define point 4 as shown in view D.
Line 1-4 is equal to line 4-2.
(3) Bisect an Angle, (figure 24).
Let's assume that we have an angle (1-0-2,
view A). Our problem is that we have to bisect this angle. To bisect this angle,
perform the following steps:
