How do you dilate shapes?
Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilations involve multiplication!

Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilations involve multiplication! Dilation with scale factor 2, multiply by 2.Click to see full answer. Also to know is, how do you get a negative dilation?If the value of scale factor k is negative, the dilation takes place in the opposite direction from the center of dilation on the same straight line containing the center and the pre-image point.One may also ask, how do you find the scale factor? To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your scale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one. Likewise, how do you dilate a rectangle on a graph? Graph the rectangle ABCD with coordinates A(-2, 1), B(1, 1), C(1, -1), D(-2, -1). Then dilate the image by a scale factor of 2 with the origin as the center of dilation. First, we start by plotting the points for the rectangle ABCD. Next, we take all of the coordinates, and we multiply them by 2.What is the scale factor of the dilation?The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs. When the absolute value of the scale factor is less than one, a compression occurs.
