7. Nabuko wants to construct a mobile out of flat triangles so that the surfaces of the triangles hang parallel to the floor when the mobile is suspended. How can Nabuko be certain that she hangs the triangles to achieve this effect?

a. She needs to hang each triangle from its center of gravity or centroid, which is the point at which the three medians of the triangle intersect.

b. She needs to hang each triangle from its center of gravity or orthocenter, which is the point at which the three medians of the triangle intersect.

c. She needs to hang each triangle from its center of gravity or centroid, which is the point at which the three altitudes of the triangle intersect.

d. She needs to hang each triangle from its center of gravity or orthocenter, which is the point at which the three altitudes of the triangle intersect.
