Question: The coordinates of the centroid of a triangle with vertices at (2, 3), (4, 5), and (6, 7) are:
Options:
(4, 5)
(3, 4)
(5, 6)
(6, 5)
Correct Answer: (3, 4)
Solution:
Centroid = ((2+4+6)/3, (3+5+7)/3) = (4, 5).

Questions & Step-by-Step Solutions
The coordinates of the centroid of a triangle with vertices at (2, 3), (4, 5), and (6, 7) are:
Step 1: Identify the coordinates of the triangle's vertices. They are (2, 3), (4, 5), and (6, 7).
Step 2: To find the x-coordinate of the centroid, add the x-coordinates of the vertices: 2 + 4 + 6.
Step 3: Calculate the sum of the x-coordinates: 2 + 4 + 6 = 12.
Step 4: Divide the sum of the x-coordinates by 3 (the number of vertices): 12 / 3 = 4.
Step 5: To find the y-coordinate of the centroid, add the y-coordinates of the vertices: 3 + 5 + 7.
Step 6: Calculate the sum of the y-coordinates: 3 + 5 + 7 = 15.
Step 7: Divide the sum of the y-coordinates by 3: 15 / 3 = 5.
Step 8: Combine the x and y coordinates to get the centroid: (4, 5).
Centroid of a Triangle – The centroid is the point where the three medians of the triangle intersect, and its coordinates can be calculated as the average of the x-coordinates and the average of the y-coordinates of the vertices.
