I like making posters, but I don't want my room to look like poster throw-up.  When I do put up a poster, I want it to apply to material that we will use throughout the course.  I also love to play around with different fonts and different font colors, so when I do make a poster, it takes me a loooong time to design it!

Anyway, I'm rambling.  Here are 3 posters I made about solving for x when angles are complementary, supplementary, or congruent.  These come up again and again in Geometry.  I think they look pretty, so I thought I'd share.  Hope you enjoy!
