Believe us the whole process is free of cost! If the scale factor is between 0 and 1, the image is a reduction (a shrink). Dilation is a non-rigid transformation, which means that the distance between points in the preimage and image don't remain the same; the preimage and image are not congruent. Also, you will notice that some factors are not changed during the transformation of the images from their original size to the modified one. substitute the values. It will even tell you if more than 1 triangle can be created. WebTo determine the coordinates of the dilated point, add the horizontal and vertical distances to the x- and y-coordinates of the center of dilation: (x', y') = (c + a (x - c), d + a (y - d)) Example: Dilate triangle ABC given vertices A (-1, 0), B (-1, 3), and C (1, -3), scale factor of 2, and a center of dilation of O (-4, -5).
