Multiplying a measure<br> by a scale to produce a<br> reduced or enlarged<br> measure
svetoff [14.1K]

Answer:

we conclude that:

  • If the scale factor > 1, the image is stretched
  • If the scale factor < 1, the image is reduced
  • If the scale factor = 1, the image and object will be congruent

Step-by-step explanation:

A dilation is a transformation which generates an image that is the same shape as the original object but in a different size.

The image can be obtained by multiplying the measure of the original object by a scale factor.

If the scale factor > 1, the image is stretched

If the scale factor < 1, the image is reduced

If the scale factor = 1, the image and object will be congruent

For example, if we multiply the measure of the coordinates of the vertex A(2, 2) of a triangle by a scale factor of 2, the image A' is stretched as the scale factor > 1.

Dilation with scale factor 2, multiply by 2.

  • (x, y) → (2x, 2y)

A(2, 2) → (2(2), 2(2)) = A'(4, 4)

So, the image point A'(4, 4) is enlarged.

Dilation with scale factor ½, multiply by ½.

  • (x, y) → (½x, ½y )

A(2, 2) → (2(1/2), 2(1/2)) = A'(1, 1)

So, the image point A'(1, 1) is reduced.

Therefore, we conclude that:

  • If the scale factor > 1, the image is stretched
  • If the scale factor < 1, the image is reduced
  • If the scale factor = 1, the image and object will be congruent

Help as soon possible thank you ​
Sergeeva-Olga [200]

<u>Answer:</u>

The correct answer option is D. (-2, 1).

<u>Step-by-step explanation:</u>

We are given the coordinates of the square A"B"C"D" after the rule is applied and we are to find the coordinates of the vertex A.

For that, we will reverse the rule.

A" = (-5, -3)

x: - 5 + 4 = -1

y: - 3 + 1 = -2

Now we will reverse the 90 degrees counter in counter clockwise rotation:

(x, y) ---> (y, -x)

(-1. -2) ---> (-2, -(-1)) = (-2, 1)
