RTI 4.4 Congruence and Transformations

Which of the statements is true about the graphed triangles?

Dilate the figure by a scale factor of 3 with the origin as the center of dilation. What are the coordinates of the image?

A(3,3) B(6,6) C(9,3) #3

Describe the transformations that map ABC onto A"B"C". #8

Which of the following are congruence transformations?

What is the transformation from Triangle ABC to Triangle A''B''C''? #27

What is the ordered pair for the final location of P( 2, 3) after this series of transformations? $$\left(x,y\right)\rightarrow\left(x+2,\ y-4\right)$$  then reflected over the  $$y-axis?$$   (Reflection over y-axis (x, y) → (-x, y) #20

What is the ordered pair for the final location of P( -7, 3) after this series of transformations? $$\left(x,y\right)\rightarrow\left(x,\ y+3\right)$$  then rotated  $$270\degree$$   counter clockwise about the origin.

 270 degree CCW is (x, y) →

 (y, –x). NOT ON THE PACKET

What is the ordered pair for the final location of P( 7, -3) after this series of transformations?   $$\left(x,\ y\right)\rightarrow\left(5x,\ 5y\right)$$  then  $$\left(x,\ y\right)\rightarrow\left(-x,y\right)$$  and then clockwise  $$180\degree$$  (x, y) → (–x, –y) about the origin. #14

Figure WXYZ is transformed using the rule (x, y) → (x -4, y +2) then a reflection over the y-axis, (x, y) → (–x, y).

Point W of the pre-image is at (1, 6).

What are the coordinates of point W" on the final image? #25
