I will categorize this post as “sometimes you just need a worksheet”. #SYJNAW for my twitter peeps.
I have always kind of disliked teaching the circles unit in geometry because of all the different rules – tangent / secant angles, chord-chord sides, chord-chord angles, blah blah. This year I put together a learning segment on circles that involved satellites in geostationary orbit. It was based on my experiences working at Lockheed Martin and my engineering background. I will write about it when I have time. But for now I will just attach a couple worksheets I made of problems that I put on a homework, or threw in a test. I figured I would just share these, because you know… some times you just need a worksheet.
These problems themselves involve tangents, central angles, and trig functions. The actual learning unit is very similar, but requires the students to contextualize and decontextualize. So without further comment – here’s some of the practice problems I used:
