PatrickJMT - scroll down to "algebra". There are some geometry videos in the trigonometry section. Search for the topic you are needing.
MathTV - This site is good for both algebra and geometry. Find the topic you are needing and then find an example that looks like what you are trying to solve. What I like about this site is that several different teachers explain the same example. You will start to determine which one(s) are the most helpful. This is a GREAT site for examples in Spanish!!!
VirtualNerd - Good site for both algebra and geometry. Choose your course then your topic.
PurpleMath - Good site for both algebra and geometry. Click your course along the left side then scroll down until you find the chapter topic you are needing.
