I have been a tutor and taught two liberal arts students. Like you, neither of them is good at solid geometry. How do they solve these problems? For example, sometimes the condition of the question is not mentioned, but the picture looks like two parallel lines or two faces as a known condition. Of course, this proves that the problem is not rigorous and even prone to mistakes.

If you have a good spatial thinking ability, you can generally avoid the common mistakes I mentioned above in solid geometry (that is, you can see a picture and think with the conditions given by the topic, which can prove that these two lines are actually not parallel), but for you liberal arts students, your spatial thinking ability is definitely not as good as that of science students. The cultivation of your thinking is not a day or two, so I think liberal arts students should also have their own liberal arts students.

I'll give you some advice. When doing this topic, the pictures on the test paper can be used as reference pictures. You can draw another picture by yourself according to the topic, and then prove that every step should have a basis. This is the most important thing, that is, you can only use the conditions and some properties given by the topic to deduce and prove, and don't create conditions out of thin air! ! Still use the conclusion to be proved as a condition! !

Another possibility is that you may hate doing math problems or just do it in this respect, but you have to understand that if you don't do it or understand it, you will never understand it, which is equivalent to leaving yourself with a time bomb. If you do, you can exercise. It may take you half an hour or 65,438+0 hours to understand it at first, but you have gained something, and then you will be impressed next time. If you do too much, you will be conditioned to see problems. In fact, it is no exaggeration to say that mathematics is practiced!
