- Follow the Instructions to solve this problem.

- Follow the Instructions to solve this problem.

- Bisect twice. The first perpendicular bisector divides the
segment into two equal parts. The next perpendicular bisectors
will break each of those segments into two parts for a total of four.

- Follow the instructions for problem 3. Then bisect the four
segments. The third set of bisectors will create eight equal
segments.

- Average: sum of the two lengths divided by two. Construct a
segment of length
*a*+*b*. Bisect the segment to get the average length.
