Scale factor
Next, you’ll learn how to perform the following operations:
- Determine the scale factor for the transformation.
- Identify the type of dilation.
- Draw a dilation using a scale factor.
- Find the ratio of perimeters for two dilated figures.
Center of dilation
What is another real life example of dilations? What is a real life example of a dilation or stretch? There is another example. It is dilated cardiomyopathy, a disease of the heart where the left ventricle, in most cases, stretches and thins. When you need to enlarge a picture from wallet-size to wall-hanging size, you could use dilation.

- Rotation. The sprocket of a bicycle rotates while riding the bike and pushing the pedals. ...
- Reflection. The rim an tire can be a example of reflection and rotation too!
- rotation #2. Another example of rotation can be a fan because it rotates and makes air for us in everyday life!! ...
Relative distances
Dilation. In mathematics, dilation is a type of transformation in which the size of a shape or geometric figure is changed, but the relative proportions and shape remain the same. Below are several examples. The quadrilateral and cube above are dilated to produce smaller versions of the respective shapes.
A dilation stretches or shrinks the original figure

What is an example of dilation in math?
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. An example of dilation math is 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.
How do you dilate by a scale factor of 2?
To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2. I plotted all the new points to find the new triangle. To dilate the figure by a factor of 2, I will multiply the x-value of each point by 2.
How do you calculate dilation?
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states.
What is a dilation of 1 2?

We are basically multiplying each x and y by 1/2 orMoreNow we have to dilate to a factor of 1/2. So. We are basically multiplying each x and y by 1/2 or dividing by 2 so 1/2 times 2 or 1/2 of 2 is 1.
How do you do a dilation of 1 2?
If the scale factor is 1/2, then every coordinate point of the original triangle is multiplied by the scale factor 1/2. Dilation with scale factor 1/2, then multiply by 1/2.
How do you dilate by 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 a dilation of a graph?
Dilations. A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size. The scale factor of a dilation is the factor by which each linear measure of the figure (for example, a side length) is multiplied.
