Move the cursors in the box below and get an understanding for what a 'dilation' is in geometry.
Below is a more formal version of a dilation. Let's take a closer look at exactly what is going on here!
1

The origin (0,0) has an effect on the size of the image.

1

What should we set k equal to if we want the image to be the exact same size as the preimage?

1

A dilation will result in an object congruent to the original.

1

Which transformation changes the orientation (order of the letters) in the shape?

1

What does is it mean to have a dilation factor of 3 ?

1

Use a graphboard to model and answer the question.

Start with the point A(2, 3) and dilate the point by a factor of 4 about the origin (0,0).

What are the coordinates of A' which is the image under this dilation?
