"Where, although it's just a simple method, it's not easy to figure it out."

During a few conversations, Christina had already called an old man to rush in. The old man was covered in white beard and white hair. He seemed quite knowledgeable, but his eyes were a little arrogant. He was named Stanley Wiffle. When Catherine introduced the two, he looked very disdainful of Tang Yi in his eyes.

Such emotions are understandable. Tang Yi just laughed it off. Anyway, he came to be the referee, so he should try to be fair in the game. But Christina moved out a stack of parchment paper, a bottle of ink and two quill pens from the cabinet next to her and put it down on the big table next to her: "That's good, Ayi, you are the referee, so let's ask you to give a question first and let us solve it. When we finish solving it, we will give each other a question until someone can't solve it. How about it?"

She was asking Tang Yi, but her eyes were provocatively looking at the old man named Stanley. Tang Yi smiled. She asked, "It's not good to have this kind of question, but I'm just a referee..."

"It's okay, kid, just give me one." The old man was speaking, looking at Tang Yi with disdain in his eyes, obviously seeing his guilt, and he was somewhat doubtful whether he really had knowledge of knowledge. Tang Yi couldn't help but feel a little embarrassed. In fact, the reason why Christina made this suggestion was that Tang Yi was the lowest, so that both of them could solve it when he asked him to give the question, so that they could find out the other party's bottom. Seeing Tang Yi's expression, he came over and whispered, "Ah, don't you, right?" His expression was quite nervous.

Tang Yi was the one she called. If Tang Yi was a fool, she would naturally have no face, but the old man smiled softly. Tang Yi pondered for a while, picked up the quill pen, and thought to make a simple question. Anyway, they would not be embarrassed if they solved it.

I picked up the pen, but didn't know what to write. After all, he didn't understand the words of this world at all. After thinking for a while, he asked: "You know what this... do you know what a right angle? Uh... Look, the angle of the table is called a right angle..."

"Of course I know, do you think we are mentally retarded? Write it soon." Christina jumped and protested. Stanley snorted coldly again, obviously treating Tang Yi as an idiot. But Catherine watched with great interest. She didn't understand erudite knowledge, so she just thought it was watching a show.

Tang Yi sighed, shrugged, and drew a crooked right-angle triangle on the parchment paper: "Hey, this angle is a right angle. If the length of this right angle side is three and the length of this right angle side is four, you have to calculate what the length of this oblique side is? How about it?"

As soon as he said that, both of them frowned. Tang Yi thought to himself: The simplest geometric law of hooking three, four, five, shouldn't be too difficult for people. After thinking for a while, he added: "Don't draw it and measure it with a ruler!"
