Crop Circle Confessions

The authorities have gathered sufficient evidence to arrest you for vandalism to Farmer Escott’s hay field.
They have witnesses that place you at the scene of the crime. Your shoes and clothes have hay and dirt that matches that found in the field. They have found a giant compass behind your house that has your fingerprints. They’ve got you!
You have pled guilty to the misdemeanor operating a compass without a geometer’s license. In exchange, you will be sentenced to 200 hours of community service, harvesting and bailing hay for Mr. Escott. You have also agreed to explain how you created the crop circles, so that future acts of vandalism can be prevented. When you fulfill this sentence, your record will be cleared.
In your explanation, the authorities are interested in the following information:
- How did you create the circles?
- What did you do first?
- How many people do you need to create them?
- How long did it take?
- How did you see in the dark?
- How did you avoid making foot prints to and from the field?
- Provide a scale model sketch of your crop circle plans, including
- the radius and diameter of the circles
- label parallel and perpendicular lines
- label triangles, including the measurements of their angles
- show any collinear points
- identify intersections of lines
