Відповідь:

кути А та В, бо медіпна з висотою збігається тільки у рівнобедреного трикутника, тому 2 кути обов'язково є

Объяснение:

Медіана збігається з висотою, якщо трикутник:

а) рівносторонній; тоді всі кути гострі і мають по 60 градусів

б) рівнобедрений; тоді два кути при основі рівні і обов"язково гострі, тому що тупий або прямий кут в рівнобедреному трикутнику може бути лише кутом при вершині.
