Задача. На сторонах равностороннего треугольника 𝐴𝐵𝐶 отмечены равные отрезки 𝐴₁𝐴₂ = 𝐵₁𝐵₂ = 𝐶₁𝐶₂ так как показано на рисунке. Прямые 𝐴₁𝐶₂, 𝐶₁𝐵₂, 𝐵₁𝐴₂ образуют треугольник 𝑋𝑌𝑍. Докажите, что углы треугольника, составленного из отрезков 𝐴₁𝐶₂, 𝐶₁𝐵₂, 𝐵₁𝐴₂ равны углам треугольника 𝑋𝑌𝑍.

Asked about its stance on disinformation, Telegram spokesperson Remi Vaughn told AFP: "As noted by our CEO, the sheer volume of information being shared on channels makes it extremely difficult to verify, so it's important that users double-check what they read." Overall, extreme levels of fear in the market seems to have morphed into something more resembling concern. For example, the Cboe Volatility Index fell from its 2022 peak of 36, which it hit Monday, to around 30 on Friday, a sign of easing tensions. Meanwhile, while the price of WTI crude oil slipped from Sunday’s multiyear high $130 of barrel to $109 a pop. Markets have been expecting heavy restrictions on Russian oil, some of which the U.S. has already imposed, and that would reduce the global supply and bring about even more burdensome inflation. The account, "War on Fakes," was created on February 24, the same day Russian President Vladimir Putin announced a "special military operation" and troops began invading Ukraine. The page is rife with disinformation, according to The Atlantic Council's Digital Forensic Research Lab, which studies digital extremism and published a report examining the channel. Update March 8, 2022: EFF has clarified that Channels and Groups are not fully encrypted, end-to-end, updated our post to link to Telegram’s FAQ for Cloud and Secret chats, updated to clarify that auto-delete is available for group and channel admins, and added some additional links. But Kliuchnikov, the Ukranian now in France, said he will use Signal or WhatsApp for sensitive conversations, but questions around privacy on Telegram do not give him pause when it comes to sharing information about the war.
