| After doing this | Your work should look like this | |
|---|---|---|
| Start with a line segment PQ that we will copy. | [画像:Geometry construction with compass and straightedge or ruler or ruler] | |
| Step 1 | Mark a point R that will be one endpoint of the new line segment. | [画像:Geometry construction with compass and straightedge or ruler or ruler] |
| Step 2 | Set the compasses' point on the point P of the line segment to be copied. | [画像:Geometry construction with compass and straightedge or ruler or ruler] |
| Step 3 | Adjust the compasses' width to the point Q. The compasses' width is now equal to the length of the line segment PQ. | [画像:Geometry construction with compass and straightedge or ruler or ruler] |
| Step 4 | Without changing the compasses' width, place the compasses' point on the the point R on the line you drew in step 1 | [画像:Geometry construction with compass and straightedge or ruler or ruler] |
| Step 5 | Without changing the compasses' width, Draw an arc roughly where the other endpoint will be. | [画像:Geometry construction with compass and straightedge or ruler or ruler] |
| Step 6 | Pick a point S on the arc that will be the other endpoint of the new line segment. | [画像:Geometry construction with compass and straightedge or ruler or ruler] |
| Step 7 | Draw a line from R to S. | [画像:Geometry construction with compass and straightedge or ruler or ruler] |
| Step 8 | Done. The line segment RS is equal in length (congruent to) the line segment PQ. | [画像:Geometry construction with compass and straightedge or ruler or ruler] |
