Irokoizata wa Subete Sakuzu de Kaiketsu Kanou de Aru Koto no Shoumei (Proof Geometric Construction Can Solve All Love Affairs) (Bằng chứng rằng hình học có thể giải quyết tất cả các vấn đề tình yêu) - Gumi Music: Yoh Takahashi Lyrics: 僕は数学を愛している ただ一つの答えを求めている しかしもっと愛しているのは 幼なじみの女子 今日も必死のアピール 素敵なひし形のイヤリングだ ４辺の長さは同じ 向かい合えば平行 あっちもこっちも平行 対角線はそれぞれの中点で垂直に交わり しかも角を二等分 なんて美しい図形! なんて美しい図形! "そうなんだ.." なぜドン引きする? ねじれの位置にいるみたいな顔をするな 戸惑う僕を鼻で笑う女子に人気の顔面黄金比（イケメン） もしや貴様もこの子を狙っているのか? 作図だ! 二人を結ぶ線の真ん中に 絶対に越えられない壁を築く （１）あの子を中心にコンパスで円を （２）あいつを中心に同じ大きさで （３）２つの交点を結べば 垂直二等分線の完成だ 見たか、数学の力を 君が筋肉の力で壊したけど 今日はあの子が生まれた日 ホールケーキを贈るサプライズ 自分で８割食べちゃった点を抜けば 完璧なプレゼント 完璧なプレゼント "半分こしよ" そっけなく君は言う 僕は８割食べたからもういいっての "バカ" 何だと? 僕の数学力をペガサスとすると 君はさしずめ粘液を放つ上かわいい虫 作図だ! 二等分などロポニッチョにおける パーラマハモルゲルほど容易いのだ （１）とんがりを中心に円を （２）２つの交点から同じ大きさで （３）その交点ととんがりを結べば 角の二等分線の完成だ ケーキはもうぐちゃぐちゃだから 君は浮かない顔をしているけど * * *やっちまった! 数学のせいで嫌われる一方 昔は良かった 手を繋いで写真も撮った 赤い糸なんて曖昧なものではなく 確かな線分で結ばれていると思っていた 作図だ! 思い出の写真真っ二つにして この恋をきっぱり０にしてしまおう （１）線分上の手を中心に円を （２）２つの交点から同じ大きさで （３）その交点と手を結べば 垂線でお別れだ 捨てた写真 それを目にしたあの子は 泣き出しそうな顔で走り去った 君を見失ってしまったが 大通りで見たという証言 ここからの最短ルートは 垂線だ 作図だ! 僕が数学に目醒めたのは 君への最短距離を見つけるためだったんだ （１）ここ中心にあの道にかかる円を （２）２つの交点から同じ大きさで （３）その交点をめがけて走る 木々をかき分けて 枝が刺さる 痛みはない 疲れもない あるのは 数字化不可能な情熱だけ 君を見つけた 好きだと言った 君は笑った 答えは一つ Romaij: Boku wa suugaku o aishiteiru Tada hitotsu no kotae o motometeiru Shikashi motto aishiteiru no wa Osananajimi no joshi Kyou mo hisshi no apiiru Suteki na hishigata no iyaringu da Shi-hen no nagasa wa onnaji Mukaiaeba heikou Acchi mo kocchi mo heikou Taikakusen wa sorezore no chuuten de suichaku ni majiwari Shikamo kaku o nitoubun Nante utsukushii zukei!

What a wonderful diamond-shaped earring! All four sides are the same length, And the opposite sides are parallel.. Here, there, parallel everywhere The diagonals cross each other's midpoints perpendicularly, And they even bisect the angles! Such a beautiful figure! Such a beautiful figure! "Oh, really.." Why do you recoil so? Don't give me that look like you're at a skewed position! As I puzzle, the ladies man with the perfect golden-ratio face snorts; Don't tell me, are you after her too? Geometry time! In the middle of the line connecting these two, I'll construct a wall that can never be crossed (1) Use a compass to draw a circle centered on her (2) Do the same for him, with the same size (3) Connect the two points of intersection, And you have a perpendicular bisecting line! Do you see now the power of math? Though you destroyed it with the power of muscle.. Today is the day she was born, So I surprised her with a gift, a full-size cake Ignoring the fact that I ate 80% of it myself, It's the perfect present! It's the perfect present! "Let's each have half.." You said, curtly But I already ate 80%, so I'm fine "You dummy!" What's this? If my math skills were a pegasus, Yours would surely be a mucus-spewing yet cute bug! Geometry time! Bisection? Why, roponiccho such as that Is as simple as paramahamolger! (1) Draw a circle centered on the pointed end (2) Do the same at the two intersections, the same size (3) Connect that intersection with the pointed end, And you have an angle-bisecting line! Although the cake is a mess now, So it seems you're not very happy.. * * *Now I've done it! Because of my math, now she hates me.. Things used to be better; we even took a photo holding hands Nothing so ambiguous as a red thread of fate, I thought we were connected by a definite line segment.. Geometry time! I'll cut this photo of my memories into two, And reduce this love cleanly down to zero (1) Draw a circle centered on the hands along the line (2) Do the same at the two intersections, the same size (3) Connect that intersection with the hands, And you have a perpendicular-line farewell.. But when she saw me discarding that photo, She looked ready to cry, and took off running.. Though I lost sight of you, I heard you were seen on the main street The shortest route there from here Is a perpendicular line.. Geometry time! The reason I got into mathematics Was so I could find the shortest distance to you.. (1) Draw a circle centered here across that road (2) Do the same at the two intersections, the same size (3) Run toward that intersecting point, And cut through the trees.. The branches scrape me, and I feel no pain, I feel no exhaustion, but what I do feel Is a passion that can't be put in numbers.. I found you, I told you I love you, You smiled; My one and only answer..
