Teacher Xu, Please Take Care of the Reckless Students in Your Class

Eight poles can't hit!

???????

Zhao Kailong had a question mark on his face.

He froze in place, his eyes wandering dully between Wei Minghai and the blackboard.

once……

twice……

three times……

"I don't believe it! Do you know calculus? Stop following this with me!"

"And you, Wei Minghai, did you do it on purpose! Did you look up other ways to solve this problem on the Internet before!"

"You stand up for me! I make you stand up!"

Wei Minghai sat in his seat, rolling his eyes to Zhao Kailong, "Teacher, do you think I'll be so bored that I'll search for answers in order to trouble you?"

Zhao Kailong, "!!!"

"I don't believe it! Come on! Come up and write me down the entire process of solving this problem! Immediately! Immediately!"

Wei Minghai waved his hand, "No need! Really! Teacher Zhao, it's totally unnecessary! Besides, what is there to write about such a simple question!"

puff-

Zhao Kailong almost vomited out a mouthful of old blood.

"Lawless! You are simply lawless!"

Luo Pingting glared at Wei Minghai, "Don't make trouble for Teacher Xu, hurry up!"

Wei Minghai came to power again.

But instead of answering the question, he wrote:

In acute angle △ABC, O, H, and G are the circumcenter, perpendicular center, and center of gravity of the triangle, respectively.

OD⊥BC is in D, HE⊥CA is in E, and F is the midpoint of AB.

If the areas of ΔODC, ΔHEA, and ΔGFB are equal, find all possible values ​​of ∠C.

"Mr. Zhao, I have a question, can you try it?"

Zhao Kailong was trembling all over, and the words that he said seemed to pop out of his teeth.

"I! Let! You! Do! Question! No! Yes! Let! You! Give! Me! Issue! Question!"

"You! Give! Me! Appropriate! But! And! Stop!"

Wei Minghai, "Academic exchange! Since Mr. Zhao can't, I will give the answer directly."

"There are two ways to solve this problem. The first is that the area of ​​the triangle ODC is..."

"..."

"The second way to solve the problem is, because G is the center of triangle ABC, the area of ​​triangle GFB is one-sixth of triangle ABC, so..."

"..."

"Teacher Zhao, don't treat the belly of a gentleman with the heart of a villain!"

"I will! But I think your question is simple, I just don't write it, I just play!"

Zhao Kailong blushed and had a thick neck, "You, you! Wei Minghai! You...I can't control you anymore, right!"

"You think you can take advantage of opportunities to..."

Before the words were finished, others shouted, "Teacher, Wei Minghai's thinking is very correct!"

"Moreover, the question he asked is indeed more attractive than the one you asked!"

"Yeah yeah! Teacher, do you know why we're so lackluster in your class? It's because it's too easy!"

"And your thinking is out of date! Obviously it can be different!"

too!simple!one!!

Pass!Time!!

These words came out of the mouth of the group of students, and Zhao Kailong plopped down and sat on the ground.

His mind went blank.

who am I?

Where am I?

What should I do?

His three views exploded!

The impact of these students on him is too great!

Hemp egg!
