Step 3: Where these arcs intersect, locate point D. Draw a
straight line from A to D. This line will bisect angle
BAC and establish two equal angles: CAD and
BAD.
Figure 4.10 Example on how to bisect an angleD. How to Draw an Arc or Circle (Radius) Through Three
Given Points
Given: Three points in space at random: A, Band C.
Step 1: With straight line, lightly connect points A to B, and B
to C,
Step 2: Using the method outlined for bisecting a line, bisect
lines A-B and B-C
Step 3: Locate point X where the two extended bisectors
meet. Point X is the exact center of the arc or circle.
Step 4: Place the point of the compass on point X and adjust
the lead to any of the points A, B, or C (they are the
same distance), and swing the circle. If all work is
