поризм мікеля, або ботанський погляд на поворотну гомотетію. дано n кіл ω_1, ω_2,...,ω_n що проходять через одну точку O. вторинні точки перетину(між ω_1 і ω_2, ..., ω_n і ω_1) позначимо як P_1, P_2,..., P_n. A_1 - довільна точка на ω_1, A_2 - точка перетину A_1P_1 і ω_2,..., доведіть, що точки P_{n+1} і P_1 співпадають
це не задача, а просто спостереження таке тривіальне.

On Feb. 27, however, he admitted from his Russian-language account that "Telegram channels are increasingly becoming a source of unverified information related to Ukrainian events." As a result, the pandemic saw many newcomers to Telegram, including prominent anti-vaccine activists who used the app's hands-off approach to share false information on shots, a study from the Institute for Strategic Dialogue shows. In the United States, Telegram's lower public profile has helped it mostly avoid high level scrutiny from Congress, but it has not gone unnoticed. Telegram boasts 500 million users, who share information individually and in groups in relative security. But Telegram's use as a one-way broadcast channel — which followers can join but not reply to — means content from inauthentic accounts can easily reach large, captive and eager audiences. That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future.
