Chapter 100 Got 63 points!
The two auxiliary lines connecting the circumscribed circle and the inscribed circle are set by Fang Chao as a little cutie and a little bow tie.

The cutie bypasses the circumscribed circle and left its heavy make-up on point P, but left two points on the inscribed circle, named as cutie 1 and cutie 2.

This question is to calculate the two angles between two points less than or equal to 30°.

There are also two geometrical arithmetic problems to prove.

The two auxiliary lines drawn by Fang Chao looked more complicated on this geometric diagram, but in Fang Chao's eyes, they became more beautiful, like a tool that made this question more complicated. A few ideas come out, this is very important.

Afterwards, Fang Chao drew four auxiliary lines. On this basis, a similar parallelogram was born. It is the twin brother of this geometry problem. It was made by Fang Chao. The originally complicated body shape started to look a lot easier.

He does not need to fight alone, but has this twin brother to fight with him.

When the GM assigned this question, there were too many BUGs, or in other words, these BUGs existed, and there was no way for them to be eliminated, but they were well hidden by the GM.

The first thing the players have to do is to find these hidden auxiliary players.

It took Fang Chao nearly 10 minutes to break through the checkpoints, and finally rescued the twin brother.

The twin brothers looked at Fang Chao and felt the power of the 2B pencil in his hand. It was one of the most feared artifacts by the God of Mathematics. It could destroy the world and create mathematics, but it could also destroy it.

With 2B in hand, the world has me.

In particular, it can feel the strength of Fang Chao, the host holding the 2B pencil, which should not be underestimated. This should be a powerful host. Otherwise, how could he have rescued himself from the hiding place in such a short period of time.

In order to fight against the last boss named 'Answer', the twin brothers looked at Fang Chao, and Fang Chao also looked at the twin brothers.

Twin Brother: I see you are paralyzed...

Fang Chao: Get out!

Twin brother: Forget it, I won’t leave. If I leave, I won’t be able to deal with the 'Answer' BOSS. Although I find you very unhappy and feel that you are very good at showing off, your level of showing off is based on your strong mathematics skills. Maybe the two of us join forces and we can get the 'answer' done.

Fang Chao: What do you want to say?
Twin Brothers: Do you have a double row?

Fang Chao: Yes.

Therefore, Fang Chao and his twin brothers formed a double row, and with the help of the twin brothers, Fang Chao's combat effectiveness soared.

He used Ptolemy's theorem to cleverly calculate the relationship between the angles and side lengths of two parallelograms, and thus calculated the sine and cosine values, which made the boss lose blood continuously under the siege of the two, and wiped out at a distance Apparently not far away.

Half an hour has passed, and Fang Chao is dripping with sweat. This question is really not easy, it is too difficult to solve, and it will definitely not be any easier than the first question. If you want to talk about these three questions, the last one The finale is the most difficult, followed by the first question, and the second question in the middle is the easiest.

Fang Chao relaxed, took a sip of water, and ate another pack of spicy sticks.

Cool!
Lin Teng, you are also my good brother. This spicy strip tastes really good.

"You can still eat spicy sticks while doing the questions...you are really different..."

The tutor is about to go crazy, why don't you continue to do it halfway through the problem?You make me very tangled up like this, I want to see how you solve this problem.

Fang Chao was scared again, and his good brother was also scared away by the appearance of the mentor. It didn't know whether it was reinforcements or enemy troops, and was afraid that the duo would not only deal with 'Answer' but also this person.

The twin brothers ran away.

Fang Chao is very unhappy.

The train of thought is broken.

This teacher is really annoying. He keeps circling behind him.

Fang Chao was extremely distressed, "Teacher, don't be by my side anymore, you are affecting my thinking, I don't know how to solve the problem now... and I'm really hungry, so I just eat something Fill your hunger... I broke another 2B pencil and I need to sharpen it."

"Okay, then you continue."

The instructor also knew that some people really didn't like others staring at them when they were doing the questions, so the instructor left soon, giving Fang Chao the space to develop freely.

Fang Chao breathed a sigh of relief after repeatedly confirming that the mentor was finally not behind him.

But twin brother, come out...I can't live without you...

Frightened by their mentor, the twin brothers became cautious. Fang Chao kept searching and finally found it again. Fang Chao kept convincing the twin brothers to let him fight side by side with him again. This time, the artifact 2B pencil had changed again. Being sharp, he is fully capable of taking down the BOSS before the artifact loses its edge.

Seeing Fang Chao's determination to win, the twin brothers finally nodded and once again agreed to work together with Fang Chao.

With the help of the twin brothers, Fang Chao became obviously more cautious this time, but his fighting style became more sharp-edged.

Two auxiliary lines came out again.

Fang Chao used Simsson's theorem to get the answer to the first question.

Then he measured it with a protractor, and sure enough, it did not exceed 30°. The answer he got was the same as the conclusion, and he got a certain percentage of points.

Then, he continued to write down several steps to determine the sine values ​​of the four corners.

Using the law of sine value, the answer to the second small question is obtained.

The blood of the boss is running out, and it has been killed one after another. It can be seen that it is very weak now.

Adhering to the idea of ​​"killing you while you are sick", Fang Chao took drastic measures and used all the theorems to finally solve the remaining two small problems.

Boss blood is empty! !

Get it!

The twin brothers bid farewell to Fang Chao, thanking him for his help this time.

So it was printed on the test paper like this.

Fang Chao put down the artifact 2B pencil. After this battle, its body was less than one-third of its original size, and it was very weak. The time to fight was running out. Fang Chao decided to cherish the time with it, It was carefully placed in the pencil case.

At this moment, almost three hours have passed since the CMO National Finals.

On the last question, Fang Chao spent nearly an hour and a half, which was almost impossible for Fang Chao in the past, because he would take more than an hour for no question, and one can imagine how difficult the national decision is. huge.

However, Fang Chao was not in a hurry to hand in the papers. This competition was of great significance to him. He began to re-examine and re-test the questions. After about 10 minutes, Fang Chao knew that this was the first day of the national finals.

Three questions.

The full score is 63 points,
Get it!
