Final answer:
To calculate the centroid of a complex shape, find the average x-coordinate and average y-coordinate of all the points in the shape.
Step-by-step explanation:
The centroid of a shape is the average position of all the points in that shape.
To calculate the centroid of a complex shape, you need to find the average x-coordinate and the average y-coordinate of all the points in the shape.
For example, if you have the points (4,3), (3,4), (5,5), and (2,2), you would add up the x-coordinates and divide by the number of points to find the average x-coordinate. Then you would do the same for the y-coordinates to find the average y-coordinate. In this case, the centroid would be (3.5, 3.5).
