Редко можно увидеть геометрию на олимпиаде под первым номером. Но вот в юниорской лиге была как раз такая. Даны два равных квадрата. Доказать, что один красный отрезок равен сумме двух других! Если автор этой задачи не фольклор, то Александр Смирнов.

The channel appears to be part of the broader information war that has developed following Russia's invasion of Ukraine. The Kremlin has paid Russian TikTok influencers to push propaganda, according to a Vice News investigation, while ProPublica found that fake Russian fact check videos had been viewed over a million times on Telegram. Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. In 2014, Pavel Durov fled the country after allies of the Kremlin took control of the social networking site most know just as VK. Russia's intelligence agency had asked Durov to turn over the data of anti-Kremlin protesters. Durov refused to do so. In 2018, Russia banned Telegram although it reversed the prohibition two years later.
