Summary[edit]
DescriptionPerth Impossible Triangle.jpg |
English: Impossible Triangle sculpture, put together by Brian MacKay & Ahmad Abas, located in the Claisebrook Roundabout, East Perth, Perth, Western Australia. Seen from the correct angle, this sculpture seems to be a Penrose triangle עברית: פסל "משולש בלתי אפשרי" כאשליה אופטית, במזרח העיר פרת', מערב אוסטרליה. מזוויות מסוימות נראה שהקורות נפגשות בקודקוד העליון, אף על פי שאין זה כך, וכך נוצרת אשליית משולש פנרוז. |
