Geometry Notes

geometry notes, geometry notebook

In Geometry Notes, we have answered the classical and new generation questions that are highly likely to appear in exams. We did this with a clear and simple explanation without causing confusion. More importantly, it is among our aims to enable you to look at the problems from a broad perspective and to interpret them correctly.

Even if you’re a student in a classroom, if you don’t take math-geometry grades properly and always write them on the back of the paper, you don’t have the concept of “review” or “topic repetition”, so you won’t have grades. If you don’t understand something in a topic or problem, be it a Mathematics-Geometry course or any other course, you tend to get bored with writing notes. If you quit, you won’t even think about going back and reviewing it later. Even if you don’t understand a problem during class, when you get home, you can look at your notebook and say, “It’s really simple!” you might think! Please do your best not to leave your geometry notebook empty.
