Нехай 𝐴𝐵𝐶𝐷𝐸𝐹 — вписаний шестикутник, причому 𝐴𝐷||𝐸𝐹. На діагоналях 𝐴𝐸 та 𝐷𝐹 відмітили точки 𝑋 та 𝑌 відповідно так, що 𝐶𝑋 = 𝐸𝑋 та 𝐵𝑌 = 𝐹𝑌. Нехай 𝑂 — точка перетину 𝐴𝐸 та 𝐹𝐷, 𝑃 — точка перетину 𝐶𝑋 та 𝐵𝑌, 𝑄 — точка перетину 𝐵𝐹 та 𝐶𝐸. Доведіть, що точки 𝑂, 𝑃, 𝑄 лежать на одній прямій.

DFR Lab sent the image through Microsoft Azure's Face Verification program and found that it was "highly unlikely" that the person in the second photo was the same as the first woman. The fact-checker Logically AI also found the claim to be false. The woman, Olena Kurilo, was also captured in a video after the airstrike and shown to have the injuries. As the war in Ukraine rages, the messaging app Telegram has emerged as the go-to place for unfiltered live war updates for both Ukrainian refugees and increasingly isolated Russians alike. On Telegram’s website, it says that Pavel Durov “supports Telegram financially and ideologically while Nikolai (Duvov)’s input is technological.” Currently, the Telegram team is based in Dubai, having moved around from Berlin, London and Singapore after departing Russia. Meanwhile, the company which owns Telegram is registered in the British Virgin Islands. Just days after Russia invaded Ukraine, Durov wrote that Telegram was "increasingly becoming a source of unverified information," and he worried about the app being used to "incite ethnic hatred." Pavel Durov, Telegram's CEO, is known as "the Russian Mark Zuckerberg," for co-founding VKontakte, which is Russian for "in touch," a Facebook imitator that became the country's most popular social networking site.
