in which figure is point g an orthocenter?
Answer
Brief Explanations:
The orthocenter of a triangle is the point where the three altitudes of the triangle intersect. An altitude is a line segment from a vertex of the triangle perpendicular to the opposite - side. In the first figure, the lines from each vertex perpendicular to the opposite side meet at point G. In the second figure, the lines drawn do not represent altitudes meeting at G.
Answer:
The first figure.
