# Program to find the Centroid of the triangle

Given the vertices of the triangle. The task is to find the centroid of the triangle:**Examples:**

Input: A(1, 2), B(3, -4), C(6, -7) Output: (3.33, -3) Input: A(6, 2), B(5, -9), C(2, -7) Output: (6.5, -9)

**Approach:**Suppose if the vertices of a triangle are (x1, y1) (x2, y2) (x3, y3) then centroid of the triangle can be find from the following formula:
