He is measuring how much the factor increased so for example 1/3 being divided by 3. Where AC , CE, AB, and BD are the point to point lengths shown on the triangle below. Our change in, or even If they are similar, identify the corresponding sides of the triangles. So our scale factor right over here is 1/3. A center of dilation can either be part of the preimage or outside of the preimage. If they are similar, identify the corresponding sides of the triangles. So with the preimage being larger, the dilation has to be a fraction less than 1. So, the coordinates of the vertices of the dilated triangle A B C are A'(0, 16), B'(16, 0) and C'(0, -16). Identify the original points of the polygon. They do not affect the calculations. Enter the dilation point in the dilation box.
