The purple shape is a dilation of the black shape. What is the scale factor of the dilation?<\/p>\n\n\n\n Find the length of one side in the original shape.<\/p>\n\n\n\n The side connects (–<\/sup>1, –<\/sup>2) and (1, –<\/sup>2). It is 2 units long.<\/p>\n\n\n\n Find the length of the corresponding side in the image.<\/p>\n\n\n\n The side connects (–<\/sup>5, –<\/sup>10) and (5, –<\/sup>10). It is 10 units long.<\/p>\n\n\n\n Write the ratio of the length in the image to the length in the original figure.<\/p>\n\n\n\n 10\/2<\/p>\n\n\n\n Simplify the fraction.<\/p>\n\n\n\n 10\/2=5<\/p>\n\n\n\n The scale factor is 5.<\/p>\n<\/div><\/div>\n\n\n\n The orange shape is a dilation of the black shape. Is it an enlargement or a reduction?<\/p>\n\n\n\n The orange shape is larger than the black shape. So, the dilation is an enlargement.<\/p>\n\n\n\n You can check your answer by finding the scale factor. Find the length of one side in the original shape.<\/p>\n\n\n\n The side connects (–<\/sup>3, –<\/sup>3) and (3, –<\/sup>3). It is 6 units long.<\/p>\n\n\n\n Find the length of the corresponding side in the image.<\/p>\n\n\n\n The side connects (–<\/sup>9, –<\/sup>9) and (9, –<\/sup>9). It is 18 units long.<\/p>\n\n\n\n Write the ratio of the length in the image to the length in the original figure.<\/p>\n\n\n\n 18\/6<\/p>\n\n\n\n Simplify the fraction.<\/p>\n\n\n\n 18\/6=3<\/p>\n\n\n\n The scale factor is 3. Since the scale factor is greater than 1, the dilation is an enlargement.<\/p>\n<\/div><\/div>\n\n\n\n The green shape is a dilation of the black shape. Is it an enlargement or a reduction?<\/p>\n\n\n\n The green shape is smaller than the black shape. So, the dilation is a reduction.<\/p>\n\n\n\n You can check your answer by finding the scale factor. Find the length of one side in the original shape.<\/p>\n\n\n\n The side connects (–<\/sup>10, –<\/sup>10) and (–<\/sup>10, 5). It is 15 units long.<\/p>\n\n\n\n Find the length of the corresponding side in the image.<\/p>\n\n\n\n The side connects (–<\/sup>2, –<\/sup>2) and (–<\/sup>2, 1). It is 3 units long.<\/p>\n\n\n\n Write the ratio of the length in the image to the length in the original figure.<\/p>\n\n\n\n 3\/15<\/p>\n\n\n\n Simplify the fraction.<\/p>\n\n\n\n 3\/15=1\/5<\/p>\n\n\n\n The scale factor is 1\/5. Since the scale factor is greater than 1, the dilation is an enlargement.<\/p>\n<\/div><\/div>\n\n\n\n let’s practice!<\/p>\n\n\n\n Dilations: scale factor and classification The scale factor of a dilation is the ratio of a length in the image after the dilation to the corresponding length in the original figure. Learn with an example The purple shape is a dilation of the black shape. What is the scale factor of the dilation?
