Нехай 𝐵𝐸 та 𝐶𝐹 — медіани гострокутного трикутника 𝐴𝐵𝐶. На прямій 𝐵𝐶 обрали точки 𝐾 ≠ 𝐵 та 𝐿 ≠ 𝐶 такі, що 𝐵𝐸 = 𝐸𝐾 та 𝐶𝐹 = 𝐹𝐿. Доведіть, що 𝐴𝐾 = 𝐴𝐿.

The fake Zelenskiy account reached 20,000 followers on Telegram before it was shut down, a remedial action that experts say is all too rare. Ukrainian forces have since put up a strong resistance to the Russian troops amid the war that has left hundreds of Ukrainian civilians, including children, dead, according to the United Nations. Ukrainian and international officials have accused Russia of targeting civilian populations with shelling and bombardments. Again, in contrast to Facebook, Google and Twitter, Telegram's founder Pavel Durov runs his company in relative secrecy from Dubai. Perpetrators of these scams will create a public group on Telegram to promote these investment packages that are usually accompanied by fake testimonies and sometimes advertised as being Shariah-compliant. Interested investors will be asked to directly message the representatives to begin investing in the various investment packages offered. But the Ukraine Crisis Media Center's Tsekhanovska points out that communications are often down in zones most affected by the war, making this sort of cross-referencing a luxury many cannot afford.
