Question

Determine which rectangle was transformed to result in rectangle E

Answer 1

Rectangle B!!!!

Explanation:

I took the QUIZ Trust me :)

Answer 2

Rectangle C

Explanation:

Rectangle C was transformed to Rectangle E.

To see how this occurs, let's follow point F (-2, 5) through the two transformations.

(a) Reflection across the x-axis

The x-coordinate does not change, but the y-coordinate changes sign.

Thus, F ⟶ F' (-2, -5).

(b) Translating up two units

The x-coordinate does not change, but the y-coordinate increases by 2..

Thus, F' ⟶ F" (-2, -3).

You can follow the same transformations for the other three corners of rectangle C.

Rectangle C ⟶ Rectangle E
