What is Dilation in Math?
A dilation in math is an enlargement or reduction of a figure about a center of dilation by a specified scale factor, k. It is a type of transformation that creates similar figures. The original figure will either grow in size or shrink, depending on the scale factor.
Scale Factor of Dilation
The scale factor of dilation describes the change in size of the figure. A scale factor that is x > 1 (greater than 1) is an enlargement. A scale factor that is 0 < x < 1 (greater than 0 but less than 1) is a reduction. Scale factor is often described using the variable k.
How to Find the Scale Factor of a Dilation
To find the scale factor of a dilation, identify a pair of corresponding sides. Corresponding sides are those that are in the same location in both the original and new figures. Determine the length of the corresponding sides of both the original and new figures. The scale factor is found by using the ratio of new length to original length.
How to Find the Center of Dilation
The center of dilation is often the origin, (0, 0), when on a coordinate plane, however, it can be any fixed point on the plane. This is the point in which all points are enlarged or reduced and can be located inside, outside or on a given figure. To determine the center of dilation, find the scale factor using two corresponding sides.
How to do Dilations
Dilations off of the coordinate plane can easily be completed. The designated scale factor, k, describes the reduction or enlargement that needs to take place. Using the side lengths, you will multiple the scale factor by each dimension. All sides of the figure must be dilated by the same scale factor in order to develop the similar figure.

What is dilation in photography?
What is a Dilation? A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of each type of dilation (one that gets larger and one that gest smaller). Example 1.
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. Compare the side length of the real object to the length of the corresponding side in the representation.
How to find scale factor of similar figures?
You calculate the scale factor of similar figures by taking the ratio of corresponding parts of the two figures. When enlarging the shape, the larger measurement is the numerator, and the smaller measurement is the denominator. When shrinking the shape, the smaller measurement is the numerator, and the larger measurement is the denominator.
What is scale factor?
A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. If the scale factor is a whole number, the copy will be larger. If the scale factor is a fraction, the copy will be smaller. A scale factor ratio can be expressed as a fraction, 1 2 1 2, or a colon, 1: 2 1: 2.
Why is scale important?
Scale factor is how we ensure the representation of the object differs only in size from the original object.
What is scale model?
A scale model is a model accurate to a scale factor. If the copy of the actual object is not made to scale, it will look unrealistic, like a little child's toy. One object can have different scales too. The greater the difference between the two numbers of the ratio, the smaller the model will be.
What is 1: 87 scale?
A model that is 1: 87 1: 87 is generally going to be a lot smaller than a model with a ratio of 1: 12 1: 12. To make scale models, you need accurate plans of the original item, like a scale drawing. A scale drawing is an accurate plan of the real object, drawn using a scale factor to make the drawing small enough to handle.
What is ratio in math?
A ratio measures the relationship between two things. You could create a ratio of left-handed students to all students, but that ratio is not a scale factor.

What is scale factor?
Scale factor is a number by which the size of any geometrical figure or shape can be changed with respect to its original size. It is the ratio of the sizes of the original figure with the dilated figure.
What is dilation in geometry?
Dilation Geometry. Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor. For example, a square of side 5 units can be dilated to a square of side 15 units, but the shape of the square remains the same. 1. Dilation Definition. 2.
How many units are in a dilated square?
Dimensions of the new shape = Dimensions of the original shape × Scale factor. Substituting the values in the formula: The length of the dilated square = 5 × 4 = 20 units. Therefore, the length of each side of the new dilated square will be 20 units.
What is the center of dilation?
The resizing happens from a point called the center of dilation. It is the center of dilation from which the objects/figures are expanded or contracted.
What is the scale factor of a dilation?
Scale factor: The scale factor is the ratio of the distance from a center of dilation to a point on the dilated image and the distance from a center of dilation to the corresponding point on the original image. The scale factor is also the ratio of the lengths of the corresponding sides of the dilated image and the original image. If scale factor > 1, the dilation is an enlargement where the dilated image is larger than the original image. If scale factor < 1, the dilation is a reduction where the dilated image is smaller than the original image.
What is dilation transformation?
Dilation: A dilation is a transformation that maps point {eq}P {/eq} to point {eq} {P}' {/eq} with scale factor {eq}k {/eq} and center of dilation {eq}O {/eq}. A point {eq} {P}' {/eq} is mapped so that {eq}O, P, {/eq} and {eq} {P}' {/eq} are on the same line, and {eq}frac {overline {O {P}'}} {overline {OP}} = k {/eq}.
What is the horizontal distance from (0, 0) to (4, 4)?
The horizontal distance from (0, 0) to (4, 4) is 4. The vertical distance from (0, 0) to (4, 4) is also 4. Multiplying these distances by the scale factor {eq}frac {1} {4} {/eq} gives us the horizontal distance of 1 and the vertical distance of 1.
Answer
This would mean that you are to shrink the size into the existing image/shape to create the new shape. if the number is less than one, you are to shrink the size; if the number is more than one, you are to enlarge the size. If the number is indeed one, the size stays the same.
