When K=1 (the dilation scale factor is 1), the image does not change: A scale factor one 1 is uncommon, because it doesn't change anything! But when K>1 (the dilation scale factor K is a number that is larger than 1), the image will be stretched! If K=2, the image is stretched twice as large as the original!

Triangle P′Q′R′ is a dilation of triangle PQR with scale factor 2. Point C is the center of dilation. Step 1 : Use a ruler to measure segments CP, CP', CQ, CQ', CR and CR' to the nearest millimeter. The triangle DEF is a dilation of the triangle ABC with center O and with ~ 3. It is defined as the fixed point in a plane where all points are either expanded or contracted. When the ~ is greater than 1, the image is a streched.

Dilation - A transformation that may change the size of a figure. -The picture below shows a dilation with a scale factor of 2. -This means that the image, A', is twice as large as the pre-image A. -A scale factor is the ratio of the lengths of corresponding sides of similar polygons or solids. -It is usually represented by the letter r. - To find the scale factor students could: a. divide 22” by 11” to get a scale factor of 2. But a scale factor of 2 would mean the other dimension would be 8 1 2 x 2 or 16” which is too large. 1 b. Divide 13” by 8 2 ” to get a scale factor of 1.53.
