What are the coordinates of the centroid of a triangle with vertices P(−4, −1) , Q(2, 2) , and R(2, −3) ?
Alenkasestr [34]

Answer:

(x,y)=(0,\frac{-2}{3})

Step-by-step explanation:

Given : Vertices of Triangle P(x_1,y_1)=(-4,-1) , Q(x_2,y_2)=(2, 2) and R(x_3,y_3)=(2,-3)

To find : Centroid of a triangle

The centroid of a triangle is the point of intersection of the three medians of the triangle.

The formula to calculate the centroid of a triangle is:

(x,y)=(\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})

Where, x_1,x_2,x_3,y_1,y_2,y_3  are the coordinates of the centroid

Substituting the values in the formula gives us:

(x,y)=(\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})

(x,y)=(\frac{-4+2+2}{3},\frac{-1+2-3}{3})

(x,y)=(\frac{0}{3},\frac{-2}{3})

Therefore, (x,y)=(0,\frac{-2}{3})
