Which sequence of transformations produces an image that is not congruent to the original figure? a. a translation of 4 units to the right followed by a dilation of 2. b. a rotation of 90 degrees clockwise followed by a translation of 2 units to the left. c. a translation of 3 units to the left followed by a reflection across the y-axis. d. a reflection across the y-axis followed by a rotation of 90 degrees counterclockwise.

The correct answer is:

A) A translation of 4 units to the right followed by a dilation of 2.

Explanation:

3 of our transformations are called isometries. These are transformations that preserve the size and shape of the original figure; they just change the position or orientation of it. Translations, reflections and rotations are all isometries. We know that isometries preserve congruence, since they maintain the size and shape of the original figure.

A dilation is not an isometry. This is because a dilation changes the size of a figure. Since the new figure will not be the same size as the original, they will not be congruent.

Which transformations will produce similar, but not congruent figures? a.) triangle mno is reflected across the x-axis and then rotated 90 degrees clockwise to form triangle m n o . b.) triangle mno is reflected across the x-axis and then translated 9 units down to form triangle m n o . c.) triangle mno is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle m n o . d.) triangle mno is reflected across the y-axis and then rotated 180 degrees clockwise to form triangle m n o .

If you rotate, translate, or reflect a figure, the afterimage will be congruent to the original.
But if you dilate the figure, you are changing the dimensions and the length of its sides. However, angle measures are preserved and therefore that makes the figure and its afterimage similar.
Therefore C.) produces a similar but not congruent figure because there is the dilation in it.

A parallelogram with coordinates A (-2,3), B (3,3), C (4,6), and D(-1,6) is the first rotated 90 degrees clockwise and then translated 4 units left and 2 units down to form quadrilateral A B C D what is the distance, in units between point C and point D in the resulting figure

Step-by-step answer

Given:

The vertices of a parallelogram are A (-2,3), B (3,3), C (4,6), and D(-1,6).

It is first rotated 90 degrees clockwise and then translated 4 units left and 2 units down to form quadrilateral A'B'C'D.

To find:

The distance between C' and D'.

Solution:

If a figure rotated 90 degrees clockwise, then

$(x,y)\to (y,-x)$

$C(4,6)\to C_1(6,-4)$

$D(-1,6)\to D_1(6,-(-1))=D_1(6,1)$

If figure translated 4 units left and 2 units down, then

$(x,y)\to (x-4,y-2)$

$C_1(6,-4)\to C'(6-4,-4-2)=C'(2,-6)$

$D_1(6,1)\to D'(6-4,1-2)=D'(2,-1)$

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between C'(2,-6) and D'(2,-1) is

$C'D'=\sqrt{(2-2)^2+(-1-(-6))^2}$

$C'D'=\sqrt{(0)^2+(-1+6)^2}$

$C'D'=\sqrt{(5)^2}$

C'D'=5

Therefore, the distance between C'D' is 5 units.
