No longer bothered with Zhou Jun, he always felt that in a short period of time, he had changed a little too much, his eyes were cold, and he felt uncomfortable when he looked at it.

Liu Meng looked at the game of ruler drawing with great interest.

"Knowing the two corners and the edges between them, seek to make a triangle, hehe, Border City, your problem is too simple, I can do it in less than three minutes." ”

......

The rules of this game are to start from one person.,After he made it.,Set a problem.,And then designate a person to solve it.,In order to pass on.,The person who fails is punished.,At the beginning, they were ordinary would-be scholars.,The question is not difficult.,Otherwise, it's not boring to pass on.,Everyone really wants to see a duel of several badge quasi-scholars.。

The game is getting more and more exciting, and when it was Yuan Hua's turn, he smiled and said: "My brother is known as the first person to make a ruler and gauge in Anxian County, hey, how bad can my brother be." ”

"The straight line OA and OB intersect at the point O, P and Q are a straight line, if you want to find a point G, the distance to the straight line OA and OB is equal, and the distance to the point P and Q is also equal, as long as the bisector of the AOB angle is made first, and then the perpendicular bisector of PQ, the intersection point is naturally the G sought. ”

Yuan Hua drew it as he spoke, and was greeted with applause.

Whew, Yuan Hua also made a question, the process is very complicated, everyone frowned when they saw it, thinking, don't click on me, you badge quasi-scholars play by yourself, it's so complicated, it takes a long time to make, and if you can't do it, you will be embarrassed.

Yuan Hua glanced at everyone behind him, and all of them turned their faces away, not looking at each other, but they didn't get chosen because of one look.

Han Shen smiled: "Don't look for me for this question, it's too time-consuming, and it's embarrassing to draw it wrong." ”

Qiu Ming smiled: "Yuan Hua, every time you do such a complicated drawing, one person will delay so much time, why don't I come." ”

Yuan Hua said with a smile: "Brother Qiuming, use a knife to kill chickens, this question is too simple for you." ”

Bai Wuyang snorted and smiled: "It's too simple." ”

Since Yuan Zhi became a true scholar, she is currently recognized as the strongest ruler in Anxian County.

Yuan Hua pointed with his hand, "Then who, Liu Meng, just come on, let's see what strength you have as a person from Bei'an City, so that we can open our eyes." ”

It was not clicked, and the people who had not participated were relieved, and they felt very inappropriate, after all, the people of Anxian County still have a sense of superiority over other acropolis.

Asked me what to do for no reason, Liu Meng walked up, took two rulers, a compass, and the two rulers were prescribed to form right angles, and quickly drew them, and it didn't take long to draw them.

Yuan Hua shouted: "You are cheating." ”

Bai Wuyang kept looking at it and said, "Opportunistic and violating the rules." ”

Tyumen looked at it and didn't speak.

"If you don't know how to draw, you can't scribble, if you give me a ruler with a scale, then any drawing is easy to do, but once measured, there will be a big error, can you still call the ruler to make a drawing?"

"Tu Baozi, I'm afraid that Bei'an City has never played with ruler and drawing. ”

They have seized the opportunity to show the superiority of the students in Anxian County.

Liu Mengdao: "Any drawing problem that is solved by using a right-angle plate can be completed only with a compass and a ruler, so using a compass, a straightedge, and a right-angle plate to draw does not bring new things to the principle of drawing, and the scope of drawing is still in the scope of ruler drawing, but the steps of drawing are greatly simplified." ”

"For example, if you make a perpendicular line from a known point, you can solve it by simply coincident one side of the right-angled plate with the known line. In this sense, the use of right-angled plates simply makes the series of steps of ruler drawing more concise and organized. ”

Everyone didn't think about this, as soon as they saw Liu Meng doing that, they took it for granted that it was not right, and when they heard this, they were stunned for a while to think, all of them have academic strengths, and they are not stupid.

Bai Wuyang said angrily: "What nonsense is just an excuse for you to be lazy, saying that you are wrong is wrong." ”

She thinks very highly of herself, she is the first person to make a ruler and a ruler, and what she says is authoritative and cannot be refuted.

"Whatever you want. Liu Meng said indifferently, it was none of my business, and I didn't like to play this kind of boring game.

What kind of attitude! Bai Wuyang was about to get angry, and he was all in a posture.

Qiu Ming opened his mouth at this moment and said: "Wuyang, there is no doubt that the right-angle plate used by Liu Meng did not damage the essence of the ruler drawing, but made the process of drawing simple, which can be used as an auxiliary tool, after all, the root of the ruler drawing is the exercise of logical thinking, and it is just a waste of time to draw a complex drawing step by step." ”

Qiuming's attainments in spatial geometry are not as good as Bai Wuyang's, but his computing power is slightly higher, he is very modest, and he is very prestigious on the second floor.

Yuan Hua said angrily: "You kid will really cheat and play tricks, count you over." ”

Liu Meng doesn't like to play this kind of game with them, it's too boring, brother's ruler is drawing, you have no problem on the street in seconds, the gap is too big.

Because of Qiu Ming's affirmation, Bai Wuyang couldn't say anything, but he was very unhappy in his heart, and his impression of Liu Meng was even worse, and he said: "If you pass it, you will come up with another question, I hope you don't laugh too much." ”

She held her breath and didn't let it out, her cheeks bulged out one after another, she was usually cute, with anger, and looked like a toad.

It's not easy to do the questions, and it's not casual.

Liu Meng quickly drew a polygon and said with a slight smile: "It's really simple, as long as you find where M and N are, let the triangle AMN have the smallest circumference." ”

This is a very regular and simple question.

"I'll come. ”

"It's so simple. ”

"Point me, not ten seconds. ”

Quite a few ridiculed voices.

"The level of drawing is not good, and the level of the question is even worse, which can roughly bluff the three-year-old baby. Bai Wuyang sneered.

"Don't worry, where are M and N, the area of the triangular AMN is the smallest, it's up to you. Liu Meng pointed to Bai Wuyang and said in his heart, how can my question be so easy to do.

It is true that the problem of the shortest triangle circumference is easy to solve, as long as the symmetry point is made, the M and N points can be found with a line, but the smallest area is difficult to visualize with graphics, Bai Wuyang didn't think of the idea for a while, and saw Liu Meng point her.

I was very angry right now.

The guy was pointing his finger at her.

And not at all respectful.

Bai Wuyang's face was slightly pale, and she shouted, "Then I'll come." ”

She thought about it, and after making the picture, she would definitely give this guy a little color, and she didn't know the punishment of humility.

Bai Wuyang originally thought that it was not too difficult, but he didn't expect to be stuck.

This card is twenty minutes without progress.

So many people waited, watched.

Full.

Countless lines were drawn, drawn and rubbed, rubbed and drawn.
