Make learning plans

Making a detailed study plan, including the tasks to be completed every day and the content of study, can help you arrange your time more orderly and improve your study efficiency.

Attach importance to basic knowledge

The eighth grade mathematics curriculum is based on a series of basic knowledge, so it is necessary to ensure the mastery of these basic knowledge. Strengthening the understanding and memory of basic concepts is the basis of establishing a higher level of mathematical understanding.

Do more exercises.

Mathematics is a subject that needs a lot of practice. Through a lot of practice, we can deepen our understanding and memory of knowledge points and improve the speed and accuracy of solving problems.

Learn to summarize.

After learning a chapter or a knowledge point, we should summarize it in time and systematize and organize what we have learned, which will help to form long-term memory and understanding.

Ask for help and advice

If you encounter difficulties or problems in your study, don't be shy or afraid. You can ask teachers, classmates or parents for help and guidance, and they will be happy to provide help and support.

Summary of eighth grade mathematics knowledge points

pythagorean theorem

1, Pythagorean theorem: the sum of squares of two sides of a right triangle is equal to the square of the hypotenuse.

2. Inverse Pythagorean Theorem: If three sides of a triangle satisfy that the sum of squares of two sides is equal to the square of the third side, then the triangle is a right triangle.

quadrilateral
