P₁ и P₂ - изогонально сопряжены в треугольнике ABC. X₁ и X₂ - проекции B на AP₁ и AP₂, а Y₁ и Y₂ - проекции B на CP₁ и CP₂ соответственно.
1) Точки X₁ и X₂, Y₁ и Y₂ симметричны относительно средней линии треугольника ABC. Если P₁ и P₂ совпадают (случай инцентра), то X₁ = X₂, Y₁ = Y₂ лежат на средней линии.
2) Обобщённые точки 255 лежат на хордах педальной окружности точек P₁ и P₂. Если A₁, B₁, C₁ и A₂, B₂, C₂ - проекции точек P₁ и P₂ на стороны BC, AC и AB треугольника соответственно, то X₁ ∈ A₁B₂, X₂ ∈ A₂B₁, Y₁ ∈ B₂C₁, Y ∈ B₁C₂.

Elsewhere, version 8.6 of Telegram integrates the in-app camera option into the gallery, while a new navigation bar gives quick access to photos, files, location sharing, and more. Pavel Durov, a billionaire who embraces an all-black wardrobe and is often compared to the character Neo from "the Matrix," funds Telegram through his personal wealth and debt financing. And despite being one of the world's most popular tech companies, Telegram reportedly has only about 30 employees who defer to Durov for most major decisions about the platform. The picture was mixed overseas. Hong Kong’s Hang Seng Index fell 1.6%, under pressure from U.S. regulatory scrutiny on New York-listed Chinese companies. Stocks were more buoyant in Europe, where Frankfurt’s DAX surged 1.4%. In view of this, the regulator has cautioned investors not to rely on such investment tips / advice received through social media platforms.
