Construction Project Using just a straight edge and compass, complete the following constructions. Basic Constructions 1. Copy a segment. 2. Copy an angle. 3. Bisect an angle. Parallel and Perpendicular Constructions 4. Construct a perpendicular bisector of a line segment 5. Construct a line perpendicular to a given line through a given point. 6. Construct a line parallel to a given line through a given point. Triangles 7. Construct an equilateral triangle. 8. Construct the translation of a triangle. Polygons inscribed in circles 9. Construct a square inscribed in a circle. 10. Construct an isosceles triangle inscribed in a circle. 11. Construct a regular hexagon inscribed in a circle. The following websites, along with the online textbook and your notes will explain how to do some of the constructions: 1. http://whistleralley.com/construction/reference.htm 2. http://www.mathopenref.com/tocs/constructionstoc.html 3. http://jwilson.coe.uga.edu/EMT668/EMT668.Folders.F97/Anderson/geometry/geometr y1project/construction/construction.html Name_______________________________________________ Per_______ RUBRIC Basic Constructions (1-3) Excellent Good Fair (5 points) All constructions are complete and accurate.
