In which figure is point G an orthocenter?


Answer:
In triangle JKH
Step-by-step explanation
The point where the three altitudes of a triangle intersect.
We need to finds altitude from those three point.
When they intersect we got orthocenter of triangle.
Altitude must form right angle with opposite side.
They must form right angle with opposite side.
So in our case G is orthocenter for JKH
