Внутри правильного шестиугольника взяли другой правильный шестиугольник, после чего соединили их соответствующие вершины. Докажите, что сумма площадей красных четырехугольников равна сумме площадей синих шестиугольников. Верно ли, что сумма квадратов площадей красных равна сумме квадратов площадей синих?

Russian President Vladimir Putin launched Russia's invasion of Ukraine in the early-morning hours of February 24, targeting several key cities with military strikes.

Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.”
