Descriptive geometry classes 6

Today I had another descriptive geometry class. This was the first class after the holidays. Despite this, as I had done some exercises during the holidays, I still remember the material studied. We reviewed some concepts about lines and learned some new things, namely parallel and oblique lines, passing and non-passing lines. It is true that good results in descriptive geometry depend a lot on regular study. In this new year, I have set myself the goal of working more often.
