How do you know if a scale factor will make a shape larger or smaller?
Pay close attention to the order of the two shapes. The first shape listed is what you start with. If the second shape is larger, the scale factor will be greater than 1. If the second shape is smaller, the scale factor will be smaller than 1.
How do you know if the scale factor is greater than 1?
If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). If the scale factor is 1, the figure and the image are congruent.
Is 4 3 an enlargement or reduction?
A scale factor of less than 1 results in a figure of reduced dimensions . A scale factor of greater than 1 would result in a figure of enlarged dimensions. As 43>1 , it would create an enlarged figure.
How do you find the scale factor less than 1?
To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your scale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one.
Is the scale factor expected to be greater than or less than 1?
The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is less than one, a compression occurs.
What is the range for the scale factor of an enlarged image?
A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image. If the scale factor is between 0 and 1 the image is a reduction. If the scale factor is greater than 1, the image is an enlargement.
