Step 4.

Draw a line through point 3 perpendicular to line 1-2 which intersects

line 1-2 (view D).

Step 5.

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:
