Step-by-step explanation:
If (x1,x2) (y1,y2) &(x3,y3) are vertices of a triangle then,
centroide of a triangle is given by the formula,
X = (x1+x2+x3)/3 &Y=(y1+y2+y3)/3
=> X = (-1+5+8)/3=4
& Y =(0-2+2)/3=0
Hence centroid of triangle (X,Y)=(4,0)
Ans. d) (4,0)

Given :-
A triangle (Δ) ABC which has the following coordinates :
- A ( - 1 , 0 )
- B ( 5 , - 2 )
- C ( 8 , 2 )
Find :-
- Centroid of ΔABC
- A ≡ A ( - 1 , 0 )
- B ≡ B ( 5 , - 2 )
- C ≡ C ( 8 , 2 )
Now, we know that :
Hence,
The coordinates the Centroid of the ΔABC is G ( 4 , 0 ) . [ option (d) ]
