Answer:
Medians
Explanation:
The center of gravity of a body is the center of mass of the body. It is the point from which the weight of the body may be considered to act.
For a body with uniform thickness and density, the center of gravity is the center of the body.
Let's see the below triangle;
From the above, we can see that the center of the triangle is the centroid which is the intersection of the three lines drawn from the vertex of one side of the triangle to the midpoint of the opposite side of the triangle. Note that these lines are called medians.
Therefore, the center of gravity of the triangular solid is the intersection of the medians of the triangle.
