Here is a Geometry Lesson I am developing.
It has placemarks for 3 rectangles, 3 triangles, 3 circles, and 5 polygons.
I'll type out the answers to the questions for each placemark below. All of the measurements are approximate though, and some have been slightly rounded so that the numbers are easier to work with.
I would have students draw out a diagram and label it of each shape as well.
I hope I got all my measurements right here. I rushed through it. Any comments, corrections, or suggestions are always welcome.

Hi JDWilliams
An interesting collection you have found there.
You may enjoy geoGreeting as it's a similar kind of thing...
In fact, I have a message for you 
Cheers,
Phil

Thanks Phil,
I've actually used GeoGreeting before with my students to practice spelling words. They thought it was a little bit more fun than just writing them down.

I really got the idea for the Geometry Lesson from the post above; the Maths in Las Vegas and Maths in Madrid posts (but there is an incredible amount of useful information and files in that link about many different subject areas. TBarrets blog is also a good read).

Great job! I plan on using you as an example as far as using google earth for math...what a wonderful lesson! Thanks for your hard work!

What an excellent example. How did you find those shapes?

Peter,
Some of them were pretty easy to find (The Pentagon, the basketball stadium at the college I graduated from, rectangles).
But, yeah, some of them were pretty difficult to find. The hexagon buildings took awhile.
I did a google search for something like "hexagon building." It actually comes up with quite a few results. The hard part was finding the good results: address of the actual buildings, then finding ones that had higher resolution images.
It pretty much just took time. But, now I can use it in my classroom every year for as long as I need to (and anyone else can use it too), and it is more engaging for the students then just a worksheet. I have a 1:1 computing environment in my classroom so I break it down to the individual folders and have my students work on them one at a time over a few weeks. By about the third folder all of them seem to know what they're doing  .
What does this all mean? Share your stuff on here. If you use mine I want to use yours so I don't have to spend that much time on each lesson... ha ha.
Edit: I also searched the forums quite a bit for keywords like circles, hexagons, pentagons, octagons..
