September 2nd Transformations Assessment Review

A transformation from C to D can be described as...

• 270 degree counterclockwise rotation

• 90 degree counterclockwise rotation

• a reflection over the x axis

• a reflection over the y axis

Given figure QERN and it's image Q'E'R'N', identify the transformation.

• 90 degrees counterclockwise rotation

• reflection across the x-axis

• 90 degrees clockwise rotation

• reflection across the y-axis

If the quadrilateral is translated 4 units to the left and 5 units down what is the coordinates for Point A'?

• (4,0)

• (0,4)

• (-1,5)

• (5,-1)

Write a rule for the translation.

•  (x -1, y  + 2)

•  (x -2, y  + 1)

•  (x +2, y  - 1)

• (x +1, y  -  2)

Find K' if the figure is reflected across the x-axis

• (4, 1)

• (-1, -4)

• (1, -4)

• (1, 4)

∆QRS contains the points: Q(4, 2) R(5, 1) S(3,7). If the triangle is reflected across the y-axis, what will S' be?

• S'(3, 7)

• S'(-3, 7)

• (x-2, y+9)

Triangle ABC is labeled with points A(5, 2), B(1, 2) and C(3, 6) on a coordinate plane. Find the coordinates of A' B' C' after a reflection over the x-axis.

• A’(5, -2) B' (1, -2) C' (3, -6) 

• A’(-5, -2) B' (-1, -2) C' (-3, -6)

• A’(-5, -2) B' (-2, -1) C' (-6, -3) 

Which of the following is the composition of a dilation by a scale factor of 4 and then a translation of 5 units down?
