| After doing this | Your work should look like this | |
|---|---|---|
| Start with a given ray. | |
|
| Step 1 | Pick a point not on the line, about 6 cm from the endpoint of the ray. Its exact location is not important. Label it D. | |
| Step 2 | Set the compasses on point D and set its width to the endpoint of the ray. | |
| Step 3 | Draw an arc that crosses the ray and extends over and above the ray endpoint. (If you prefer, draw a complete circle.) | |
| Step 4 | Draw a diameter through D from the point where the arc crosses the ray. | |
| Step 5 | Draw a line from the ray's endpoint to the endpoint of the diameter line | |
| Step 6 | Done. The last line drawn is perpendicular to the ray. | |
