# Constructions Packet

```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
