“三角形是最穩固的結構，這是因為它在形狀固定的情況下不會變形。從結構角度來看，它不需要額外的固定來保持穩定。在多變形的範圍內，三角形的形狀是唯一的，這使得它成為建構幾何體時的理想選擇。相比於其他形狀，三角形的連接處更加堅固，因此更常被選用。但是在其他條件下，不同的形狀也可能表現出穩定性。”
triangle—the most stable shape in geometry
In the world of geometry, the triangle stands out as the most robust structure. Its stability lies in the fact that once the lengths of its three sides are determined, the shape of the triangle is fixed and unique. This means that no additional bracing is required at the joints to maintain its form, as long as the lengths of the sides and the angles remain unchanged. However, when we consider deformation beyond the scope of polygons—where the sides don’t change length and don’t bend—do straight lines, circles, or halves of circles retain their stability? Is the triangle still the only stable structure in such cases?
The reason we often say that triangles are the most stable is because we are used to constructing geometric shapes with lines, and the joints are typically weaker points that require reinforcement, such as riveting or welding. But what if a polygon were forged in one piece, with all parts having equal strength? In such a scenario, where would the stability we talk about come into play? Wouldn’t the sides and angles be just as prone to deformation?

As the dawn’s early light began to fade into the shadows of the pre-dawn, Hagiwa Kenji felt a surge of irritation. Before him, the two figures, once his cherished childhood friends, now seemed to have crossed a boundary, their intimacy reaching a level that was more than just a friendly embrace. It was a sight that stirred unease within him, a reminder of the preciousness of what he held dear and the fear of losing it to someone else.
As the last of the line’s heirs, he had witnessed the grand ambition of the organization that had brought him back from the brink of death—an ambition that had spanned half a century, seeking to humble the very gods themselves. Despite his disdain for the organization and his certainty that it would eventually crumble, the specter of the silver bullet, the one that could bring it all down, had yet to materialize. For now, he would not allow anything, no matter how trivial the risk, to bring that vision to fruition.

As the world’s last surviving deity, Zifu felt a constant ache in her head. The price for her resurrection had been the transformation of her gentle little magician into a malcontented monster. How could anyone withstand such a transformation? She mused, her beloved little friend must be terrified. Thus, Zifu embarked on a perilous quest to soothe the beastly ire of her savior. But as she worked, a peculiar realization dawned on her—the ire seemed to be growing rather than diminishing.
—The shadows of the once frail prime minister loomed over her, his wheelchair a silent sentinel. With the blade of a knife pressed against his thigh, he spoke in a soft whisper, “Zifu, if you dare to leave, I will take your recovered leg with you.”
—The thespian turned screen legend, once so adept at playing the fool, now toyed with a chopstick, poking at the red braised crucian carp on the table. “I wonder,” he mused with a sigh, “what the taste of a Jinx fish might be like, if it could indeed turn one’s fortune.”
Zifu gasped. The thoughts in her little friend’s mind were growing increasingly dangerous! How could she possibly navigate these treacherous waters without losing herself?

當談到結構強度和穩定性時，三角形是被廣泛認可的最佳選擇。在工程和建築領域中，三角形的穩固性是如此重要，以至於它成為了一種黃金法則。
無論是橋樑、建築物還是其他結構，三角形都能提供出色的支撐和耐力。
三角形之所以具有強大的結構穩定性，是因為它的幾何特性。三角形有三個頂點和三條邊，頂點之間總是相互連接，形成一個緊密的網狀結構。
這種連接方式使得任何外部力量都可以均勻地分散到三個邊上，從而增加結構的強度和耐久性。
此外，三角形的形狀使得它能夠抵抗變形和扭曲。當一個三角形受到壓力或拉力時，其三個頂點保持固定的位置，這使得結構更加穩定。
相比之下，其他形狀，如四邊形或多邊形，容易因受力不均而變形或變形。
三角形的穩固性可在許多實際應用中得到驗證。以橋樑為例，許多橋樑結構都使用三角形形狀的橋塔或支撐結構。
這種設計選擇不僅能夠承受來自車輛和風的力量，還可以抵擋可能的地震力量。同樣地，建築物的結構也常常使用三角形形狀的支撐柱和牆壁，以增加建築物的穩定性。
三角形的優勢還體現在其節約材料和成本的能力上。由於三角形結構的穩定性，可以使用更少的材料來建造結構，同時維持足夠的強度。
總之，三角形作為結構的最穩固選擇已經得到了廣泛的證明。無論是在工程領域還是建築領域，採用三角形形狀的結構可以提供卓越的支撐和穩定性，同時也具有節約材料和成本的優勢。
