The first question is geometric proof, with a value of (15) points. On the test paper, a cylinder is drawn, and a triangle is inlaid in it. It is required to prove that the midpoint of the triangle is perpendicular to the midpoint of the cylinder.
The second problem is cone analysis (25 points)
The third problem is to prove that the cube is perpendicular to the plane (35 points)
Fourth question
Emmmmm。
Qin Luo quickly made the answer.
Are you sure it's a competition question, not a bonus question?
Qin Luo's mouth twitches, left to see, right to see.
Then the corners of Qin Luo's mouth twitch more severely.
The brother on the left is sweating, the little sister on the right is frowning. The handsome young man in front is pale. His right hand holding the pen trembles violently, as if he will faint in the next second.
"Bang!" All of a sudden, a heavy weight fell to the ground. In front of Qin Luo, the pale handsome boy fell to the ground.
“……” Others ask for money, but you ask for life.
It seems to have long been used to this kind of thing, invigilator teacher did not even lift his eyelids, waved, two medical staff quickly sent the handsome boy out.
"This is the 8th ~"
"ha ha, last year, 18..."
From afar came the voice of the nurse's little sister.
"Bang!" Another big bang.
Someone fainted again?
Qin Luo quickly recalled, but what appeared in front of him was the invigilator's cold eyes.
"Don't look around."
"Cough, teacher, I want to hand in my paper."
“……” The invigilator's mouth twitched and his face was livid.
Looking at the time, 2.28, 28 minutes before the beginning of the exam, even less than half an hour.
You can't copy the answers so fast, can you?
Without saying a word, he reached for the test paper.
Multiple choice, fill in the blanks, calculation, geometric analysis
There is not a single piece of paper left behind!
He did not speak, slowly put down the test paper, and pointed to the classroom door.
"Thank you, teacher."
Qin Luo packed up his study supplies and left the examination room.
-
"someone has come out again. How many people have been carried out? 8, or 9? " In the pavilion not far from the examination room, several students were whispering.
They are not others. They are really the elite of Beishan No.2 Middle School.
"This test is so simple, the difficulty is lower than last year. I don't know why someone fainted."
"Well, there are always some students who are making mischief..."
“……”
"Bang!" At this time, the entrance door of the examination room was pushed open again, and they all looked at the past.
"The ninth..."
The next second, however, they all gaped.
This time, there was no medical staff, only one student in the uniform of Beishan NO.4 middle school.
“…… Beishan NO.4 middle school! When did such a great man come out? "
"Well, I think he is a salted fish to make up for the number."
"Yes, with the strength of Beishan NO.4 middle school, it is possible to hand in the paper so soon?"
“……”
After a brief silence, they burst into a burst of laughter.
Although Beishan NO.4 middle school is also one of the key senior high schools in Beishan City, it is still far from its No.2 Middle School.
Their words did not have the slightest cover up, Qin Luo who walked out of the examination room naturally heard it.
He disdained to smile, step a turn, toward the pavilion.
"Ding, we detect the mockery of the underachievers. The task is open. Please crush them. Reward: 500 points for basic learning, one chance to draw."
(ask the host to crush them with fractions and ridicule Xueba. There is only one way to die.)
