What are the coordinates of the centroid of a triangle with vertices at (1, 4), (5, 8), and (6, -3)?
Answer and explanation
Correct answer: A. (4, 3)
- Step 1: Centroid = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/3). Step 2. x = (1 + 5 + 6)/3 = 12/3 = 4; y = (4 + 8 - 3)/3 = 9/3 = 3. Answer: (4, 3). Why not the others: (6, 4.5) divides by 2.
