What happens when a scale factor is greater than one?

What happens when a scale factor is greater than one?

When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is equal to one, neither an expansion nor a compression occurs.

What does it mean when the scale factor is less than 1?

If the scale factor is less than 1, the dilated figure is smaller than the original, if it is greater than 1 the dilated figure is larger than the original.

What does a scale factor of 1 mean?

As an example, think of two squares that are similar. One has a side length of 2 inches and another has a side length of 4 inches. This gives a scale factor of 1 : 2 from the small square to the large square.

What is an example of a scale factor less than 1?

Scale factor: Smaller figure dimensions ÷ Larger figure dimensions. The scale factor for scaling down is always less than 1. For example, if the dimension of the smaller figure is 8 and that of the larger one is 24, let us place this in the formula which makes it: 8 ÷ 24 = 1/3.

What happens when the scale factor is less than 1 but greater than zero?

If the scale factor is less than 1 , then the image formed is going to be smaller than the original image. If △ABC is a triangle that has sides 4,2,6 and is reduced to a second triangle, say △A’B’C’ , with a scale factor of 12 , then △A’B’C’ will have dimensions of 2,1,3 , with the corresponding sides of △ABC .

What is the scale factor of the enlargement?

When describing enlargements you must state by how much the shape has been enlarged. This is called the scale factor. For example, a scale factor of means that the side-lengths of the new shape are twice the side-lengths of the original.

What is a scale factor of 2?

For example, a scale factor of 2 means that the new shape is twice the size of the original. A scale factor of 3 means that the new shape is three times the size of the original.

Are scale factors always less than 1?

Thus, we can see that the scale factor is greater than 1. Scale Down – This means that a larger figure is reduced to a smaller one. Scale factor: Smaller figure dimensions ÷ Larger figure dimensions. The scale factor for scaling down is always less than 1.

When the scale factor is less than 1 is it a reduction?

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.

What happens to the copy when it is created with a scale factor greater than 1 less than 1 exactly 1?

The size of the scale factor affects the size of the copy. When a figure is scaled by a scale factor greater than 1, the copy is larger than the original. When the scale factor is less than 1, the copy is smaller. When the scale factor is exactly 1, the copy is the same size as the original.

When is a figure scaled by a scale factor greater than 1?

When a figure is scaled by a scale factor greater than 1, the copy is larger than the original. When the scale factor is less than 1, the copy is smaller. When the scale factor is exactly 1, the copy is the same size as the original. . Triangle .

What is the scale factor for scaling down?

The scale factor for scaling up is a ratio greater than 1 1. The scale factor for scaling down is a ratio of less than 1 1. Once you know which way you are scaling, you compare corresponding sides using the correct basic equation.

How does the scale factor affect the size of a copy?

Draw the scaled copy. The size of the scale factor affects the size of the copy. When a figure is scaled by a scale factor greater than 1, the copy is larger than the original. When the scale factor is less than 1, the copy is smaller. When the scale factor is exactly 1, the copy is the same size as the original. . Triangle .

What happens when the scale factor of an image is less than zero?

Note that the scale factor cannot be less than or equal to zero (this would completing eliminate the figure). If K=1/2, the image shrinks to half of its original size. When shrinking a figure, the scale factor is greater than zero, but less than one.
