The mid points of the sides of a triangle are `(5, 7, 11), (0, 8, 5) and (2 ,3,-1)`Find its vertices and hence find centroid.

Explanation

To find the vertices of the triangle given the midpoints of its sides, we can follow these steps:

### Step 1: Define the vertices
Let the vertices of the triangle be:
- \( A(x_1, y_1, z_1) \)
- \( B(x_2, y_2, z_2) \)
- \( C(x_3, y_3, z_3) \)
