Построение перпендикуляра

Шаг 1: С помощью циркуля проведём полуокружность с центром в точке P, получив точки А и В.

Шаг 2: Не меняя радиуса, построим две полуокружности с центром в точках A и В соответственно, проходящими через точку P. Кроме точки P есть ещё одна точка пересечения этих полуокружностей, назовём её Q.
