Orthocenter
The orthocenter of a triangle is the point where all three of its altitudes intersect. An altitude is a line drawn from a vertex perpendicular to the opposite side. The orthocenter can be inside, outside, or on the triangle, depending on its shape (acute, obtuse, or right). It is a key point in triangle geometry, helping to understand the triangle’s properties and relationships among its angles and sides. The orthocenter’s location is related to the triangle’s angles and differs from other notable points like the centroid or circumcenter.
