Chapter 40： Taunting Xueba, there is only a dead end (1/2)

The first question is a geometric proof question, worth (15) points. A cylinder is drawn on the test paper, 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 question is the cone analysis (25 points)...

The third question, prove that the cube is perpendicular to the surface (35 points)...

Fourth question...

Emmmmm.

Qin Luo quickly made the answer.

Are you sure this is a contest question, not a sub-question?

The corner of Qin Luo's mouth twitched, and he looked left and right.

Then Qin Luo's mouth twitched more severely.

The buddy on the left was sweating profusely, the young lady on the right frowned, and the handsome boy in front was pale, and his right hand was shaking violently, as if he would faint in the next second.

”Bang!” Suddenly there was a sound of a heavy object landing. In front of Qin Luo, the pale little handsome guy fell to the ground.

”...” Others ask for money to do the problem, and you have a life to do the problem.

It seemed that he had become accustomed to such things. The invigilator didn't even lift his eyelids and waved his hand. The two medical staff hurriedly sent the little handsome boy out.

”This is the eighth one~”

”Hehe, 18 last year...”

The voice of the young lady nurse talking from afar.

”Bang!” There was another loud noise.

Someone fainted again?

Qin Luo quickly returned to his senses, but what appeared in front of him were the cold eyes of the invigilator teacher.

”Don't look around.”

”Ahem, teacher, I want to hand in the paper.”

”...” The corners of the invigilator's mouth twitched and his face was blue.

I looked at the time, 2.28, 28 minutes have passed since the start of the exam, not even half an hour.

Even if you copy the answer, you can't be so fast, can you?

Without saying anything, he reached out and picked up the test paper.
