WebLet's now have a look at a simple example with a positive scale factor and a centre not at the origin. Consider a triangle with vertices located at X = ( 0, 3) Y = ( 2, 4) Z = ( 5, 2). The centre point is defined as C = ( − 1, − 1) and the scale factor is r = 0.75. Sketch the pre-image and image on a graph. WebThe basic formula to find the scale factor of a dilated figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape. For example, if a square is dilated and …
