(Recently Revised!) This is a game I use with my students to review trig ratios. The game is played like around the world... two students go against each other, the first to say (or write) the answer wins and moves on to challenge the next student. There are 50 slides, plenty to engage a whole class for 50 minutes. The revised version is bold, clear, and easy to read on a white background. There are also several types of right triangles in various orientations to keep things exciting. Enjoy! And I almost forgot... answers are included in the notes view on PowerPoint.
I actually used these as separate problems for different teams. I have also used it in three groups - one for initial check for understanding - one for homework - and one for review. It is a very flexible product! Thanks.
Here's how I have played it in the past:
1. Students sit in their seats.
2. One student begins by standing next to one of the seated students.
3. Put up the question, and the first to say the correct answer wins. (I print out the slide show ahead of time so I don't have to calculate on the spot)
4. If the standing student wins, they continue to the next seated student
5. When the standing student loses, they take the seated person's place and the new winner continues around the room (hence the name, around the world)
6. My classes were 50 minutes, so after let's say 30 minutes of game play, whoever won against the most people wins!
My students really enjoyed this game and it was also a good way for them to review and have to quickly figure out the trig functions.

This game was a lot fun to play in the class as teams...however, it would have been better if there were more different sizes/orientations of the triangles, and some of the fill colors for the triangles were too dark -- I needed to lighten them so the students could see the right angle sign in order to identify the hypotenuse.
Thanks for your question! The slides are currently set up so that students can find the ratios in simplest form. The answers that I provide are all based on ratios, not angle measures, but you could easily adapt any of the slides to ask about angle measures as well. I like the ratios because students don't need a calculator, but adding another round of angle measures could be fun! Hope this answers your question.
