Question

The orthocenter of an obtuse triangle always lies __________.

Answer 1

The intersection of three altitudes of a triangle is called the orthocenter, while altitude is the line drawn from one of the vertex of a triangle and extends it in such a way that it cuts perpendicularly the opposite side of the same triangle.

 For obtuse triangle, the orthocenter always lies outside of the triangle. So option “C” is correct.
