"How do you do this?"

Just started to do it, Ye Qingqing ran into an obstacle horse, and a three-dimensional geometry could not be done.

In fact, she didn't understand it at all, but only understood that it was an irregular three-dimensional shape, as if there was a sphere in a cuboid, and then there was a triangle, to verify that the length of a certain two lines was equal.

Forehead...... The person who wrote the question must have a disease in the brain, and the identification is complete!

The length is different, the ruler is not enough, and you still need to spend so much effort to verify?

I really don't know what the point of studying these topics is?

She just wanted to learn medicine, and she resigned herself to organic chemistry, but how many cents are there to learn these strange graphics?

What is it related to?

Ye Qingqing scratched his scalp helplessly, and simply took a ruler to measure, this time it's good, he has discovered a new continent!

"This topic is wrong, it's obviously not the same length, and let me verify it, the person who wrote the question has a sick brain, right?"

Ye Qingqing pointed to the figure and shouted, measured it again, and said while measuring, "Look, this line is 2.1 centimeter, this line is 2.2 centimeters, a difference of one millimeter, a millimeter of error!" ”

It's so unrigorous!

"You're drilling the horns!" Lu Mo is very busy.

The mind is all used in the crooked ways, no wonder the results have to be counted backwards.

Ye Qingqing didn't follow it, and said confidently: "I have a rigorous learning attitude, one millimeter is a thousand microns, one million nanometers, and 100 million picometers, what a big omission, if you make a mistake by one millimeter when launching the rocket, the rocket was originally launched to the moon, maybe it can be turned to Mars......"

"It's just a typographical error, what are you doing on the moon and Mars?"

Lu Mo's heart was even more congested, he was really smart and useless on the right path, he remembered the conversion units of micro, nano and picometer clearly, but he didn't study well, and he broke so many crooked reasons!

Ye Qingqing sniffed and said in a low voice: "Anyway, it's wrong, I don't think there is any need to verify this question anymore!" ”

"Who said you had to study hard yesterday?" Lu Mo's tone was stern.

It's now the third year of high school, if this girl doesn't have to study hard, let alone medical school, I'm afraid that she won't even be able to pass the most advanced specialty, and with this girl's learning attitude, even if she repeats her studies for another year, she may still not be able to pass the exam.

Although learning is not the only way to succeed, this girl has such a good medical talent, it would be a pity not to go to medical school, Lu Mo firmly believes that after Ye Qingqing goes to medical school for formal training, he will definitely achieve higher achievements!

He must strictly supervise this girl's studies and strive to make a comeback in the last year!

Ye Qingqing trembled, lowered his head weakly, and said in a muffled voice: "I'll do it now, and I didn't say I wouldn't do it!" ”

Lu Mo hooked his lips with satisfaction, and after reading the question, he took a pencil and added a line to the figure, "Geometry can add auxiliary lines, add a line here, is there two more equilateral triangles?" According to the principle that the sides of an equilateral triangle are equal in length, the two lines must be equal. ”

This topic is actually very simple, it can be said to be an introductory question of three-dimensional geometry, I didn't expect Ye Qingqing, a sophomore in high school, to not do a simple question in the first year of high school, how bad her grades are, you can imagine it!

Lu Mo felt that the burden on his shoulders was much heavier, with Mount Tai on his left shoulder and Mount Hua on his right shoulder, there was a long way to go!

Ye Qingqing's eyes widened, and she heard in a daze, the three-dimensional geometry was too abstract, and she was stunned that there were two equilateral triangles?

What is the difference between adding this line and not adding it?
