Question

What is the final transformation in the composition of transformations that maps pre-image ABCD to image A"B'C"D"?

a translation down and to the right
a translation up and to the right
a 270° rotation about point B'
a 180° rotation about point B'

Answer 1

Answer:

  270° rotation about point B'

Step-by-step explanation:

Point B' is common to the last two figures, so is the center of rotation. Each of the segments of the figure A"B'C"D" is rotated clockwise 90° from the corresponding segment of A'B'C'D'. A 90° clockwise rotation is the same as a 270° counterclockwise rotation. The appropriate choice is ...

  a 270° rotation about point B'
