Question

Which of these terms does not describe polygon A'B'C'D ?

A) rotation
B) image
C) preimage
D) transformation

Answer 1

Hence, Option: C is correct.

The term that does not describe polygon A'B'C'D' is:

Pre-image.

Explanation:

Clearly we could observe that the polygon A'B'C'D' is the image that is obtained by the applying some transformation to the polygon ABCD.

The transformation that is applied to ABCD to obtain A'B'C'D' is:

Rotating the figure anticlockwise 90° and then translating it 7 units to the left and 1 unit downward.

Hence, Polygon A'B'C'D' is not a pre-image.

Since it is an image which is formed or obtained by applying required transformation to the pre-image ABCD.

Answer 2

I think the correct answer from the choices listed above is option C. The rem preimage does not describe polygon A'B'C'D'. The preimage is the original figure prior to a transformation. In the example below, the transformation is a rotation and a dilation. Hope this answers the question.
