The boss starts with brushing achievements

Chapter 10 This Fluid Feeling
The question Chidron wanted to ask was a geometric proof.

As shown in the figure: [Figure]

It is known that O is the center of the semicircle, C and E are two points on the circle, CD⊥AB, EF⊥AB, EG⊥CO.

Proof: CD = GF.

He didn't solve this problem when he solved it by himself. CD and GF are two lines that are completely different from each other, so how to prove that they are equal?
Zidron's first thought was that the triangles are similar, but there are no similar triangles on the picture.

This shows that either his thinking is wrong, or he needs to make auxiliary lines to create a pair of similar triangles out of thin air.

I don't know if he was a little confused today. He drew many auxiliary lines in his mind and didn't have any ideas.

He saw Xue Mo talking passionately with his female classmates, surrounded by a group of Yingying and Yanyan, and he was so jealous that he wished for a real PK.

Xue Mo looked over "coldly", his gaze slightly cold.

Cough cough, real person PK is not done by a gentleman, of course I have to beat him in IQ!

This question is the battlefield of the two!

Xue Mo's eyes narrowed slightly, he thought for a while, and felt that he couldn't favor one person over another and engage in gender discrimination, so he nodded and agreed.

Moreover, the questions asked by Qi Delong must be difficult questions. Although the simple questions are easy to do and the progress is fast, Xue Mo still likes the subtle excitement brought about by conquering difficult problems.

However, Qi Delong's faint expression twitched when he handed over the question, which made Xue Mo feel that things were not that simple.

Is he holding back a laugh?

why?
All the questions were answered the moment Xue Mo saw the question.

It turned out that they wanted to embarrass me with difficult problems.

It's a pity that embarrassment will not appear on me.

Xue Mo knew that Qi Delong had been competing with him in secret all this time, and he had acted with restraint, so why did he embarrass himself in public today?

Forget it, forget it, the human heart is much more complicated than the most difficult analytic geometry.

Prove that two line segments are equal, but the given condition is parallel?

According to the experience of doing questions in the past three years, this question should be to find similar triangles.

Um?There are no similar triangles.

So, is it going to be an auxiliary line?Then how should I draw?
Xue Mo frowned.

"Let me think about it first."

Seeing Xue Mo frowning, the corners of Qi Delong's mouth immediately curled up, and then he put away his smile, otherwise he would be suspected of his intentions.

But he thought too much, and the eyes of the female classmates were all on Xue Mo.

Qi Delong, as a ten thousand year old... cross out, as a Xueshen and Xue Mo's old opponent for many years, he knows Xue Mo better than anyone else.

This person's learning talent is not bad, much better than ordinary people, but there is still a slight gap between him and himself.

Don't underestimate this, there is sometimes a slight difference between ordinary people and geniuses.

Just like myself, when I encounter a problem, I will naturally think of the problem-solving idea. Although sometimes the idea will get stuck, I can always solve the problem after spending some time.

But Xue Mo can't do it. Doing questions depends on experience. It's okay to have similar question types in your head.

Even if there is, you will be helpless when your thoughts get stuck.

Seeing the change in Xue Mo's expression, he should have thought about this question but got stuck, so he frowned and thought.

Next, with his learning talent, he had to start with the questions, and once he changed from relying on his brain to relying on his hands, he would lose half of this PK.

After all, a genius does not need straw paper to solve the problem.

And once Xue Mo starts to do the questions, then he can suddenly realize at the right time, and in turn teach Xue Mo to do the questions, so that those girls who look at the face know that only IQ is the foundation of a boy!

Plan pass!
Frowning, Xue Mo thought for a few seconds, and found that his head did not support himself in drawing auxiliary lines out of thin air, and subconsciously started to do the problem.

He does not reject using straw paper to do questions, and he never shy away from his own shortcomings. It is a fact that he cannot use his brain to deduce the answer, but using paper to deduce the answer may not be slower than using the brain.

Moreover, the answer reflected on paper is the clearest and safest.

Just as Xue Mo was about to start writing, he suddenly remembered the "Diligence Can Make Up for One's Lack of Skills·Advanced" that he had just obtained.

The text in the description has changed from "a little" to "obvious". It should be a big improvement, right?
Why don't you use this problem to try the effect of the title?

Xue Mo immediately made a decision, and with a thought, he wore the latest title.

The clear stream that came from nowhere poured into my mind like a divine enlightenment, like a long-dry field receiving rain, like a female traffic policeman coming to a congested traffic, and the next moment, the obscure thoughts in my head suddenly became smooth.

Turns out, that's what genius feels like.

The semicircle figure in the question appeared in my mind, and the invisible brush redraws the line according to the condition of the question, making the figure more standard than on paper.

Conditions are highlighted, auxiliary lines are drawn one by one, and one by one disappears until the auxiliary line that is actually used to solve the problem is found.

Xue Mo frowned, but his eyes became brighter and brighter.

Similar, then the corresponding line segments will be proportional, so to prove that two lines are equal, there must be another pair of line segments that are equal!
Not graphically equal?
... No, it has!
The radii of the circles are all equal!
Xue Mo suddenly realized!

His expression remained unchanged, but his brows were already stretched, and only 1 minute had passed.

Not fast, not slow.

Qi Delong observed Xue Mo's expression all the time, this minute was like a year for him, he was asking every second, why Xue Mo didn't do anything yet?
But in the end, he still didn't wait for Xue Mo to make a move.

"Okay." Xue Mo said calmly.

What's up?Is it a problem?

Qi Delong couldn't accept this result. With Xue Mo's talent, it was impossible to solve the problem so quickly!

Yes, he must have done it. All the frowning and thinking just now were fishing, and he was acting out for himself.

His heart is so dirty!
Xue Mo held the problem in his hand, but he didn't draw the auxiliary line in a hurry. The most important thing about math problems is the idea, not the answer.

Step by step, he expressed the steps he had just deduced in his mind in easy-to-understand words, and then wrote out the problem-solving process.

"Oh, that's how it was done."

"Xue Mo, how did you think of it?"

"Xue Mo, you are really amazing!"

Five female students immediately came to cheer, but Xue Mo knew that they didn't understand. Some of them didn't even know what a similar triangle was and the conditions to prove that two triangles were similar.

Su Yin felt that she was out of tune with other people.

What is Xue Mo talking about?
Why are there so many lines drawn in the circle?

Why am I standing here?
Su Yin came to his senses, took a cup to fetch water, and prepared to drink it for Xue Mo after he finished speaking the questions.

Following Xue Mo's explanation, Qi Delong's expression changed from unacceptable to shocked to thoughtful.

"How did you think of it?" Qi Delong asked, with a slight astringency in his mouth.

The IQ that I have always been proud of, unexpectedly lost to Xue Mo, who is known for his hard work.

　Is it too much to ask for a recommendation ticket?The contract is coming soon, asking for an investment is not too much, right?
