what is centre of enlargement
It is the point in an enlarged image that stays in the same location as the original image.
To find the center of enlargement, you need to have both the original image and the enlarged image. Here's how you can find it:
1. Take a look at the original image and identify one point that you want to enlarge. This point is known as the "center of enlargement" or the "center of dilation."
2. Locate the corresponding point in the enlarged image. This point should be proportional to the original point and have the same location relative to the rest of the image.
3. Once you have identified the corresponding point in the enlarged image, draw a straight line connecting the center of enlargement in the original image to the corresponding point in the enlarged image. This line is known as the "enlargement line."
4. The center of enlargement is the intersection point of the enlargement line with the original image. It is the point that remains in the same location between the original and enlarged images.
So, in summary, the center of enlargement is the point in an enlarged image that stays in the same location as the original image. To find it, you need to identify a point in the original image, find its corresponding point in the enlarged image, and draw a line connecting the two. The intersection of this line with the original image is the center of enlargement.
