The point in the entire geometry problem in this tread is to figure out what is happening and to overlay a set of known coordinates and conditions on it. Once you have identified what's happening, then it's a simple matter to figure out what's going to happen. It appears to me that people are too concerned with the specific angles when they should be looking at the coordinate system (i.e., trees v forest). tedd _______________________________________________________ http://sperling.com/
