The [b]altitudes [/b]of a triangle go through a vertex and are perpendicular to the opposite side. The point where all three altidues intersect is called the [b]orthocenter. [br][br][/b]Locate all three altitudes. Where is the orthocenter currently in this triangle?[br][br]Move the vertices of the triangle to explore where the orthocenter is located for an[b] acute[/b] triangle, a[b] right[/b] triangle, and an [b]obtuse[/b] triangle.
