Question
Dilation that creates a large image is
- Reduction
- Enlargement
- Congruent
- Rigid transformation
Hint:
A dilation that creates a larger image is called an enlargement.
The correct answer is: Enlargement
When the scale factor is greater than 1, the dilation is an enlargement.
A dilation that creates a larger image is called an enlargement.
dilation that creates a smaller image is called a reduction.
A description of a dilation includes the scale factor (or ratio) and the center of the dilation.
The center of dilation is a fixed point in the plane.
Scale factor : Scale Factor is defined as the ratio of the size of the new image to the size of the old image
• If the scale factor is greater than 1, the image is an enlargement. It expands.
• If the scale factor is between 0 and 1, the image is a reduction. It contracts.
• If the scale factor is 1, the figure and the image are the exact same size (congruent).
