By the way!

It's actually right!

And if you say the correct answer so lightly without hesitation, you obviously have confidence in the answer to this question.

Damn it!

At this moment, Yang Rong cursed in her heart. How could this answer come from my mother who worked hard to calculate the formula? Why did you seem to easily solve the answer?

A six-track multiple-choice question and four fill-in-the-blank questions, it takes more than 90 minutes for normal people. You are a pervert, if you get a full mark within the specified time, you will have nothing to say, but you only spent about half of the time. Who are you humiliating you?

"Don't you think the topic of this competition is difficult?"

Fang Chao replied, "No, they are all quite simple, just one or two are special. It took me more than ten minutes to answer it."

Cao Nima!

Yang Rong really had murderous intentions at this moment.

Your sister's!

I think the simplest thing takes about fifteen minutes, while the most difficult thing here is only ten minutes.

"I don't want to talk to you anymore, I'll leave."

"Why leave?"

Fang Chao looked puzzled.

"Not a person from the same world."

Fang Chao felt very wronged. Yang Rong, please don’t do this? I used to be a poor student, but now I am working hard to do it. I never return to the road of mathematics and have barely become a math god-level existence. But you can’t feel alienated from me because of this. Everyone is a classmate... Shouldn’t the strong be destined to have friends?

It's too difficult for me...

Do I really want to continue this path?

Don't hit the wall and don't look back.

Black-faced carbon, I seem to have fallen into the turning point of life philosophy. I am so confused now. When can you give me some direction? Are academic masters destined to be lonely?

Fang Chao was confused, but time was not confused. When the second exam started, everyone returned to their seats.

The test test is multiple-choice and fill-in-the-blank questions, focusing more on basic knowledge, and making changes and utilization of basic knowledge. The test tests the candidates' understanding and application of basic knowledge.

The second test focuses on analyzing and solving problems. There are only three types of questions, all of which are answered. The content is divided into algebra questions, geometry questions, geometric algebra comprehensive questions or miscellaneous questions.

The exam time is 120 minutes, with a total score of 70 points.

The total score of the two tests totaled 140 points.

There is luck in the first try, but the second try is a real screening of talents. Those who can break through the siege in the second try are obviously people who truly have the talents of generals.

Someone was about to cry when he saw the first answer to the second test.

Why?

Why did the first question encounter geometric bodies?

Geometry problems, that is an absolute nightmare existence, much more difficult than algebra...

Mathematics is divided into geometry and algebra, while algebra is more inclined to calculations. Geometry has many requirements for candidates. Not only should it have a certain degree of thinking, logic and diffusion, but it also requires candidates to have a certain degree of research on spatial layout. In this regard, boys are more dominant, while girls are relatively weak.

Of course, there are still some controversies among scientists in this regard.

In the late 19th century, European scientists began to become interested in whether there was a difference in the intelligence of men and women. The "reliable" conclusion reached at that time was that women's brains were smaller than men, so their intelligence was weaker than men.

Fortunately, this statement is long outdated today.

It turns out that women's intelligence is not as good as men, and even surpasses many men.

But at the same time, we must also see that in today's scientific community, there are still several fortresses that women have not conquered, and mathematics is the most solid one.

It is true that no woman has won the Nobel Prize in the field of mathematics so far - the Fields Medal.

So, are women afraid of mathematics? The answers from many female mathematicians are no. But some women who choose other fields admit that they have never thought about doing mathematics.

Perhaps the biggest problem that you face in order to become stronger is probably baldness.

No woman doesn’t love beauty. Perhaps this is why the scarcity of female mathematicians is caused.

Regardless of whether men are more dominant than women in mathematics, Fang Chao began to scan questions when he got the test paper.

Geometry problem?

Haha, interesting!

Do you think I'm afraid of you?

I didn't even take the hell level test questions seriously, let alone you!

Soon, Fang Chao's eyes were on the test questions.

As shown in Figure 1-1, it is known that ad, be, cf is the height of △abc.

Prove: The three straight lines ad, be, and cf have a common point.

If the above point is called p, when the p point moves up and down within the line segment ad, the line segment be and cf that pass through the p point will also move accordingly.

Prove that ∠fda and ∠eda are always equal during the above movement.

"Tsk tsk, it's really not difficult at all. Is this the topic of the competition? It's really disappointing. I can easily get you done by using Menelaus' theorem and Seva's theorem!"

Soon, Fang Chao started writing.

(1), from △abe∽△acf, we get ae/af=ab/ac, similarly cd/ce=ac/bc, bf/bd=bc/ab.

Multiply three formulas to get ae/ec·cd/db·bf/fh=1

∴The straight line where the three highs are located is located is the same.

Immediately afterwards, Fang Chao drew Figure 1-2 based on Figure 1-1.

The extension line of mn∥bc intersects dc and de is m, n.

...

While Fang Chao was doing the test, a figure slowly walked behind him, staring at Fang Chao with a pair of dark eyes, as if he wanted to see how this person who had scored the full mark in the previous test solved the second test questions and whether it could be easily completed in a short period of time.

Fang Chao was doing the question easily when he suddenly felt a familiar gust of wind.

"Hey, teacher, why do you always stand behind me? I didn't cheat?"

The old invigilator said in a deep voice, "I just happened to come to you. When did I say you cheated? Don't you know the quietness of the exam site? Do the test well and I will continue to patrol."

After saying that, the old invigilator walked away and went to other places.

Fang Chao said 'oh', and he felt a little strange. Teacher, you have been standing behind me for more than three minutes just now. How could it be that you just passed by? Are you trying to create some psychological pressure for me? But we have no grudges, why are you targeting me?

The old invigilator changed into another place and continued to observe... secretly.

Fang Chao turned around, and the old invigilator took two more steps casually, but his eyes remained on Fang Chao's side, and I continued to observe in secret.

The first question, which originally took about ten minutes to solve the problem, was extremely delayed for three minutes, and finally wrote down the answer to the first question.

∵ad⊥mn,∴dm=dn

∴∠fda=∠eda.

Perfect.

Get the score!

(Secretly observe whether you have collected it for me...)
Chapter completed!
