I merged the study of triangle trigonometry and polygon area in my geometry class, since they go together very well. For their test, I created this multi-part area problem I like quite a bit. You can click the image to access the Geogebra sketch I used to make it on GeogebraTube if you’d like to download and modify it.

What a fantastic problem. I plan on stealing this for use with my students. Thanks for posting this!

You’re welcome! Glad you find it useful.
