The old man changed places with Wang Weimin opposite him and picked up the book Su Xiaoxiao had just finished reading, casually flipping to a page.
Seeing the content, the old man glanced at the confident woman opposite him, paused in his actions, and flipped two pages further.
Clearing his throat, he began, "Given a triangle with sides of 3, 4, and 5, determine if it is a right triangle."
Wang Weimin frowned slightly upon hearing this. Why is the old man posing a question now? Isn't this supposed to be an assessment of textbook theorems? Moreover, this problem often trips up students who confuse "conditions" and "conclusions."
The old woman next to him was bewildered, being illiterate and unable to understand, but it didn't matter. Seeing the serious expression on the teacher opposite, she figured the problem wasn't simple, which was good enough.
As long as it makes the little girl stumble, she'll be satisfied.
