I'm telling you a fact. In the first day of our school, there was a man who won the first place in grade three times in a row. Now in the third grade, he has disappeared from the top 200 in all grades (I know him very well). You are only in the first grade, and you still have a long way to go. Don't be proud.
The textbook of senior one is relatively simple. Only when you study functions and geometry in senior two and senior three can you learn real mathematics.
You said you were good at math? Wait until you can work out this problem in 20 minutes in grade three.
As shown in figure 1, if quadrilateral ABCD and quadrilateral GFED are both squares, obviously there are AG=CE and AG⊥CE in the figure.
1) when the square GFED rotates around d to the position as shown in figure 2, does AG=CE hold? If yes, please give proof; If not, please explain the reasons;
(2) When the square GFED rotates around D to the position shown in Figure 3, extend the intersection of CE and AG at H and AD at M. 。
① verification: ag ⊥ ch;
② When AD=4 and DG= radical number 2, find the length of AH.
I didn't mean to be sarcastic at all. I hope you can remember my study experience in recent years.
Anyway, since you have to write a summary, I don't know how many points you got in the exam. I don't know where your main loss is, I can only tell you the general structure.
You can write this way, stating your mistakes, why and in what step, and finding out your own shortcomings, as well as ways to improve in the future, what aspects of practice to strengthen, and the goal of the next exam.
