Review of primary trig ratios with a focus on sine and cosine ratios.  How to switch between angle and ratio on your calculator.  How to properly label the sides so that you can choose the appropriate ratio to use. Finding an angle given two sides, and finding the side give one side and the angle.
I do two word problems as well; finding the height of a splintered tree and finding the distance of a person standing under a kite.
