3D Print Panrose illusion triangle

The Penrose triangle, also known as the Penrose tribar, is an optical illusion and impossible object in geometry. It was first introduced by the mathematician Roger Penrose in the 1950s. The Penrose triangle appears to be a three-dimensional object with three straight edges forming a triangle, but upon closer inspection, it becomes clear that it cannot exist in physical reality.

The Penrose triangle is an example of a paradoxical figure, as it violates the principles of Euclidean geometry. Its construction relies on creating a two-dimensional representation that gives the illusion of three-dimensionality. The three edges of the triangle are connected in a way that creates the appearance of a continuous loop, which is not possible in a three-dimensional space without intersections or distortions.

The Penrose triangle has become a popular symbol in art, graphic design, and optical illusions due to its intriguing nature. It challenges our perception and highlights the limitations of our visual understanding.

彭羅斯三角形，也稱為彭羅斯三角，是一種光學錯覺，也是幾何學中不可能的物體。 它是由數學家 Roger Penrose 在 20 世紀 50 年代首次提出的。 彭羅斯三角形似乎是一個三維物體，由三個直邊形成一個三角形，但經過仔細觀察，很明顯它不可能存在於物理現實中。

彭羅斯三角形是一個悖論圖形的例子，因為它違反了歐幾里德幾何的原理。 它的構造依賴於創建二維表示，從而給出三維幻覺。 三角形的三個邊以創建連續環的外觀的方式連接，這在沒有交叉或扭曲的三維空間中是不可能的。

彭羅斯三角形因其有趣的性質而成為藝術、圖形設計和視覺錯覺中的流行符號。 它挑戰了我們的感知並凸顯了我們視覺理解的限制。
