The center of gravity of a triangle is also known as the centroid, the meet of the medians, the segments from the midpoint of a side to the opposite vertex.

The centroid is easily calculated from the average of the coordinates. We know the centroid is on the x axis, i.e. the y coordinate is 0. That's the equation:

Now we have the three vertices of a triangle. We can calculate the area with the shoelace formula:

(4,-1),(0,7),(2,-6)

(0,7),(2,-6),(4,-1)

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =
