A dilation is a geometric transformation that can change the size of an object and can change the location of an object. Every dilation has a center and a ratio.
• A dilation that ,makes an object smalle,r is sometimes called a ,compression, or a ,contraction,.
To dilate the points of the exercise,
We only have to multiply the factor by the x and y positions of our points

If K is a value greater than 1, the triangle will have an increase in size, but if it is between 0 and 1, the triangle will decrease in size.
