Question

Describe a possible sequence of transformations that maps Figure ABCDE ontofigure A'B'C'D'E'. Use at least two math or academic vocabulary terms in youranswer. Underline each term you use.

Answer 1

(The words in bold are math or academic vocabulary terms)

1)

The figure ABCDE is in the second quadrant, and the figure A'B'C'D'E' is in the fourth quadrant.

So the first step we can use is rotating the figure 90° clockwise, then the figure will go from the second quadrant to the first one.

Then, in order to go from the first quadrant to the fourth, another rotation would do it, but then the figures would not be in the same place, so instead we can use a reflection over the x-axis. This way, both figures will be in the same position.

So the sequence of transformations is: a 90° clockwise rotation followed by a reflection over the x-axis.

2)

The relation between the figures is that starting from ABCDE, we can do a 90° clockwise rotation followed by a reflection over the x-axis in order to tranform ABCDE into A'B'C'D'E'.
