|After doing this||Your work should look like this|
|Start with the line segment AB which is the length of the sides of the desired equilateral triangle.|
|1. Pick a point P that will be one vertex of the finished triangle.|
|2. Place the point of the compasses on the point A and set its drawing end to point B. The compasses are now set to the length of the sides of the finished triangle. Do not change it from now on.|
|3. With the compasses' point on P, make two arcs, each roughly where the other two vertices of the triangle will be.|
|4. On one of the arcs, mark a point Q that will be a second vertex of the triangle. It does not matter which arc you pick, or where on the arc you draw the point.|
|5. Place the compasses' point on Q and draw an arc that crosses the other arc, creating point R.|
|6. Using the straightedge, draw three lines linking the points P,Q and R.|
|7. Done. The triangle PQR is an equilateral triangle. Its side length is equal to the distance AB.|
