In fact, the proof questions are easier to grade, and if they are not the mid-term and final exams of the general senior high school entrance examination and college entrance examination, they are not very strict.

Therefore, when proving, you should write the words neatly, and when proving, you should think about what you have learned before, conceptual axioms and so on.

The difficulty of the first grade geometry is only congruent triangles's proof of parallelogram, and other proofs are parallel, which is not too difficult.

The knowledge in geometry is all connected. If you don't learn it well at all, you won't learn it later, which proves that high school can be used. )

That's about it. What problems can't be posted on the website for netizens to help solve difficult problems? It's just that some simple topics have been changed and the conditions have changed, which makes people rack their brains. Actually, it's very simple to think about it.

Well, I wish you good grades in the exam. Please accept it ~ ~ ~ Thank you.
