1. The problem statement, all variables and given/known data 1. How many planes are determined with 3 different lines? 2. How many planes can you determine using 1 line and 2 points which doesn't lay on the line? 2. Relevant equations 1 plane can be determined using 3 points 1 line can be created with min. 2 points 3. The attempt at a solution 1. If you ask me I would say that three different lines can create unlimited planes. In my book results it says 1 or three. 2. Again my answer would be unlimited. One line got unlimited points so I can create unlimited planes with the other 2 points. In my textbook results 1 or 2. Please help! Thanks in advance.
