Hi guys I'm looking for a website where I can review basic triangle rules such as the formulas for right triangles... I would look at a geometry book but I dont have one. Its been a long time and I need some reviewing to do. I also wanted to ask if anyone knew about the group of triangles such as one with sides measuring 4,5,3.... , 24,25, 7 etc? This are the typical SAT triangles.. and I know there is a patter but I dont know what it is. Thanks.
