Geometry Notes

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.

Here are some resources for free geometry notes:

MathPlanet: MathPlanet offers free geometry notes covering a wide range of topics, including Euclidean geometry, transformations, and coordinate geometry.

Purplemath: Purplemath offers free geometry notes that cover basic concepts and advanced topics such as proofs, circles, and trigonometry.

Math Open Reference: Math Open Reference is a free online geometry textbook that provides clear explanations and interactive diagrams for a variety of geometry topics.

Math Is Fun: Math Is Fun offers free geometry notes and interactive tutorials that cover a range of topics from basic shapes to coordinate geometry.

Khan Academy: Khan Academy provides free geometry notes and video lessons covering a range of geometry topics, from points and lines to three-dimensional geometry.

These are just a few examples of the many resources available online for free geometry notes. You can also check with your school or university’s math department to see if they offer additional resources or materials.

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.
