|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.|
