Learning the basic postulates of Geometry is something that you will have to return to, especially if you’re dealing with design and engineering disciplines. Since most of these questions are learned at school, it is helpful when you are looking through the equations, graphs, coordination systems, and more. If you need a more complex postulates geometry explanation, you have to proceed with the simple answers first and then choose something more specific. It’s the safest way to learn more complex things when you know the main postulates first. Start with the equations, look at the graphs, and you’ll get it.
