Dilations and Scale Factor A dilation is a proportional enlargement or reduction of a figure through a point called the center of dilation. The size of the enlargement or reduction is called the scale factor (the ratio of corresponding sides).

Section 9.5 Dilations Key Concept Dilation A dilation with center C and scale factor n, n > 0, is a transformation with these two properties: The image of Cis itself (that is, C' = C). • For any other point R, R' is on CR and CIR' CR' The image of a dilation is similar to its preimage. CR' = n.CR Since the scale factor is 2, the corresponding point in the image B' is twice that distance from O and lying on the same line, so OB' is 2 times 12, or 24.

Question 25 Score 2: The student gave a complete and correct response. Geometry – June ’19 [3] 25 Triangle A B C is the image of triangle ABC after a dilation with a scale factor of __1 A scale factor is the number that is used as the multiplier when scaling the size of an object. It can be used to scale objects in 1, 2 or 3 dimensions and as fractions, ratios, percentages, or decimals. When a scale factor is applied, the size of the object is increased or decreased according to the desired scale. When the scale factor is larger than 1, (uniform or non-uniform) scaling is sometimes also called dilation or enlargement. When the scale factor is a positive number smaller than 1, scaling is sometimes also called contraction. In the most general sense, a scaling includes the case in which the directions of scaling are not perpendicular.
