How do you dilate a scale factor?
Think in steps:
- Are you making a larger or smaller dilation?
- You are shrinking the original, so your scale factor will be less than a whole number.
- Next, measure (or read) any side of the figure and do some math.

What does a scale factor tell us?
A scale factor is the number that is used as the multiplier when scaling the size of an object. It can be used to scale objects in 1, 2 or 3 dimensions and as fractions, ratios, percentages, or decimals. When a scale factor is applied, the size of the object is increased or decreased according to the desired scale.
How can I check myself for dilation?
Scan how your body feels.
- Feeling like you have to vomit, having a flushed face and feeling warm to the touch can mean you’re about 5 centimeters dilated. ...
- Seeing if your face is flushed with no other signs can be a good indicator that you’re 6-7 centimeters dilated.
- Be aware that trembling uncontrollably without any other signs can indicate fatigue or fever.
How do you dilate with a scale factor of 3?
Perform a Dilation of 3 on point A (2, 1) which you can see in the graph below. Multiply the coordinates of the original point (2, 1), called the image, by 3. Image's coordinates = (2 * 3, 1 * 3) to get the coordinates of the image (6, 3).
What is dilating by a scale factor?
Dilation with Scale Factor Scale Factor is defined as the ratio of the size of the new image to the size of the old image. The center of dilation is a fixed point in the plane. Based on the scale factor and the center of dilation, the dilation transformation is defined.

How do you find the scale factor of a dilation?
The scale factor is determined by finding the ratio of coordinating side lengths where the new length is the numerator and the original length is t...
What is the center of dilation?
The center of dilation is the point in which all points are enlarged or reduced and can be located inside, outside or on a given figure.
How do you know the scale factor?
The scale factor is identified by the variable k. This value will determine if the dilation is an enlargement or a reduction.
How do you find the center of dilation and not the origin?
To find the center of dilation and not the origin, you first determine the scale factor. Once you have the scale factor, you substitute a pair of c...
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.
How to find scale factor?
The basic formula to find the scale factor of a dilated figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape.
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.
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.
