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