В тупоугольном треугольнике две из трех высот опускаются на продолжения сторон, и, следовательно, их большая часть находится вне треугольника.<br>Например, рассмотрим тупоугольный треугольник $ABC$, в котором угол $C$ — тупой (то есть $ \angle C &gt; 90^\circ $). Высота $BH$, проведенная из вершины $B$ к прямой, содержащей сторону $AC$, пересечет эту прямую за пределами отрезка $AC$. Таким образом, высота $BH$ (кроме точки $B$) будет лежать вне треугольника.<br><svg width="250" height="150" xmlns="http://www.w3.org/2000/svg"><polygon points="150,100 80,50 100,100" stroke="black" stroke-width="2" fill="#d3e4f5" fill-opacity="0.8" /><line x1="100" y1="100" x2="70" y2="100" stroke="gray" stroke-width="1" stroke-dasharray="4 2" /><line x1="80" y1="50" x2="80" y2="100" stroke="red" stroke-width="2" /><polyline points="80,92 88,92 88,100" stroke="red" stroke-width="1" fill="none" /><text x="155" y="105" font-family="sans-serif" font-size="16">A</text><text x="75" y="45" font-family="sans-serif" font-size="16">B</text><text x="105" y="115" font-family="sans-serif" font-size="16">C</text><text x="65" y="115" font-family="sans-serif" font-size="16">H</text></svg><br><strong>Ответ:</strong> да.</p>"

Решение 2. №7.5 (с. 41)

а) медиана
Нет, медиана не может проходить вне треугольника. Медиана — это отрезок, соединяющий вершину треугольника с серединой противоположной стороны. Так как вершина принадлежит треугольнику, и середина противоположной стороны также лежит на границе треугольника, то весь отрезок медианы будет находиться внутри треугольника. Это следует из свойства выпуклости треугольника: любой отрезок, концы которого принадлежат выпуклой фигуре, целиком лежит внутри этой фигуры.
Ответ: нет.

б) биссектриса
Нет, биссектриса не может проходить вне треугольника. Биссектриса угла треугольника — это отрезок, который соединяет вершину с точкой на противоположной стороне и делит соответствующий угол пополам. Как и в случае с медианой, оба конца биссектрисы (вершина и точка на противоположной стороне) принадлежат треугольнику. Из-за выпуклости треугольника отрезок биссектрисы полностью располагается внутри него.
Ответ: нет.

в) высота
Да, высота может проходить вне треугольника. Высота — это перпендикуляр, проведенный из вершины треугольника к прямой, содержащей противоположную сторону. В тупоугольном треугольнике две из трех высот опускаются на продолжения сторон, и, следовательно, их большая часть находится вне треугольника.
Например, рассмотрим тупоугольный треугольник $ABC$, в котором угол $C$ — тупой (то есть $ \angle C > 90^\circ $). Высота $BH$, проведенная из вершины $B$ к прямой, содержащей сторону $AC$, пересечет эту прямую за пределами отрезка $AC$. Таким образом, высота $BH$ (кроме точки $B$) будет лежать вне треугольника.
ABCH
Ответ: да.
