					Construction Worksheet #9 – Review                                Name _____________________
                                                                  Period ______
You have been taught 8 basic constructions. They are:
1. Copy a segment                   5. Perpendicular point on the line
2. Copy an angle                    6. Perpendicular point off line
3. Angle bisector                   7. Parallel line
4. Perpendicular Bisector           8. Trisect a line

You need to be able to do ALL of these and to apply them to do all constructions covered on worksheets #1-7.



                a                            b

                                                                              c

1. Construct a segment of length a + b.                    2. Construct and angle that is c.




3. Bisect the angle.                                       4. Bisect the segment.




5. Trisect the segment.
6. Construct a line perpendicular to b through P.    7. Construct a line perpendicular to c through R.
                                                                           

                                                        c




8. Construct a line parallel to d through T.         9. Construct an equilateral triangle.




              
                  T




  d




10. Construct a 105 angle. (Use a 60 and a 45.)   11. Write the sentence used to help us remember
                                                     the points of concurrency in triangles.
