Triangle abc is right angled at c. can you locate its orthocenter without drawing any altitude ? If so,name it.
Let ∆ABC be right angled at C.
The orthocenter of a triangle is the point of intersection of the altitudes of the triangle.
Since ∆ABC is right angled at C, CA and CB are the altitudes intersecting at C.
So, we can conclude that, the orthocenter is the vertex C itself.
