that's it
It's easy to say.
Difficult, difficult.
Especially solid geometry.
There is a good imagination.
There is a picture in your mind.
I didn't expect to draw more pictures.
Don't be lazy.
In order to better understand
Only in this way can we learn the previous geometry well.
Theorem must be remembered, although it is annoying and chaotic.
But the big questions in the exam can be proved by theorems and inferences
You will know that kung fu is not practiced for nothing.
