1. Carefully examine the problem: Before solving the geometry problem, first carefully examine the problem and understand the requirements and conditions for solving the problem. Pay attention to keywords and qualifiers to ensure accurate understanding of the problem.
2. Drawing helps solve problems: For geometry problems, drawing is a very important step. Through drawing, we can understand the problem more intuitively and find the key points and relationships of the problem. When drawing as accurately as possible, you can use tools such as straightedge and protractor to assist.
3. Use known conditions: Geometry problems usually give some known conditions, such as angle and side length. We should make good use of these known conditions and turn them into the information needed to solve the problem.
4. Using geometric theorems and formulas: Geometric problems often involve some geometric theorems and formulas, such as Pythagorean theorem and the properties of similar triangles. We should master these theorems and formulas skillfully and use them flexibly in solving problems.
5. Classification discussion: Some geometric problems need to be classified and discussed according to different situations. We should pay attention to decompose the problem into several sub-problems, solve them separately, and finally synthesize the results.
6. Pay attention to units and accuracy: When solving geometry problems, pay attention to the use of units and the accuracy of calculation. Ensure that the unit of the answer is consistent with the requirements of the question type, and keep appropriate decimal places.
7. Check the answer: After completing the geometry question, carefully check whether the answer meets the requirements of the question type and whether it is consistent with the actual situation. The correctness of the answer can be verified by reduction to absurdity or logical reasoning.
In short, the answering skills of junior high school mathematics geometry problems include careful examination, drawing to help solve problems, using known conditions, using geometric theorems and formulas, classified discussion, paying attention to units and accuracy, and checking answers. Mastering these skills can help students solve geometric problems better and improve the accuracy and efficiency of solving problems.
