Question

Find the coordinates of centroid of the triangles if points D(–7, 6), E(8, 5) and F(2, –2) are the mid points of the sides of that triangle.

Answer 1

The given points are D(–7, 6), E(8, 5) and F(2, –2).
Centroid is the meeting point of the medians.
Let the centroid be O(a, b)
$$\begin{gathered} \left(a,b\right)=\left(\frac{2+8-7}{3},\frac{-2+5+6}{3}\right) \\ =\left(1,3\right) \end{gathered}$$
