Example Questions

Example Question #2 : Describe The Effect Of Dilations, Translations, Rotations, And Reflections: Ccss.Math.Content.8.G.A.3

What is the scale of the dilation that the blue rectangle underwent to get the purple rectangle in the image provided? 


5

Possible Answers:

Correct answer:

Explanation:

A dilation creates an image of the same shape, but of a different size. Dilations are always done with a certain scale factor. Let's look at the image in the picture and determine the length and width of each of the rectangles:

6

Notice that both the length and the width of the rectangle is half in the purple rectangle, from the blue rectangle; thus the scale of the dilation is 

Example Question #4 : Describe The Effect Of Dilations, Translations, Rotations, And Reflections: Ccss.Math.Content.8.G.A.3

What is the scale of the dilation that the blue rectangle underwent to get the purple rectangle in the image provided?

Possible Answers:

Correct answer:

Explanation:

A dilation creates an image of the same shape, but of a different size. Dilations are always done with a certain scale factor. Let's look at the image in the picture and determine the length and width of each of the rectangles:

8

Notice that both the length and the width of the rectangle doubles in the purple rectangle, from the blue rectangle; thus the scale of the dilation is 

Example Question #3 : Describe The Effect Of Dilations, Translations, Rotations, And Reflections: Ccss.Math.Content.8.G.A.3

What is the scale of the dilation that the blue rectangle underwent to get the purple rectangle in the image provided? 


9

Possible Answers:

Correct answer:

Explanation:

A dilation creates an image of the same shape, but of a different size. Dilations are always done with a certain scale factor. Let's look at the image in the picture and determine the length and width of each of the rectangles:

10

Notice that both the length and the width of the rectangle triples in the purple rectangle, from the blue rectangle; thus the scale of the dilation is 

Example Question #6 : Describe The Effect Of Dilations, Translations, Rotations, And Reflections: Ccss.Math.Content.8.G.A.3

What is the scale of the dilation that the blue rectangle underwent to get the purple rectangle in the image provided? 


11

Possible Answers:

Correct answer:

Explanation:

A dilation creates an image of the same shape, but of a different size. Dilations are always done with a certain scale factor. Let's look at the image in the picture and determine the length and width of each of the rectangles:

12

Notice that both the length and the width of the rectangle quadrupled in the purple rectangle, from the blue rectangle; thus the scale of the dilation is

A dilation creates an image of the same shape, but of a different size. Dilations are always done with a certain scale factor. Let's look at the image in the picture and determine the length and width of each of the rectangles:

16

Notice that both the length and the width of the rectangle quadruples  in the purple rectangle, from the blue rectangle; thus the scale of the dilation is 

Example Question #9 : Describe The Effect Of Dilations, Translations, Rotations, And Reflections: Ccss.Math.Content.8.G.A.3

What is the scale of the dilation that the blue rectangle underwent to get the purple rectangle in the image provided? 


17

Possible Answers:

Correct answer:

Explanation:

A dilation creates an image of the same shape, but of a different size. Dilations are always done with a certain scale factor. Let's look at the image in the picture and determine the length and width of each of the rectangles:

18

Notice that both the length and the width of the rectangle is five times the size in the purple rectangle, from the blue rectangle; thus the scale of the dilation is
