1. Compass Constructions

2. Copying A Segment

3. Step #1:
Start with the original segment

4. Step #2:
Using a straightedge, draw a line that is longer than the original segment

6. Step #3:
Place the needle of the compass on point A and the pencil on point B

8. Step #4:
Transfer the distance to the drawn line, making an arc

9. Step #5:
Label the new points A’ and B’. Then erase the excess line.

10. Bisecting a Segment

11. Step #1:
Place the needle of the compass on point B and the pencil on a point about 3/4 across the segment

12. Make a semi-circle

13. Step #2:
Maintaining the same distance on your compass, repeat step #1 from point A

15. Step #3:
Label the points of intersection of the semi-circles points C and D

16. Step #4:
Using a straightedge connect points C and D

17. is the perpendicular bisector of
