Question

Which statement is true about the result of a rigid transformation? (4 points)

The image will be larger than the pre-image.

The pre-image will be larger than the image.

Each one is unique; no general statement can be made about size.

The pre-image will be congruent to the image

Answer 1

In a rigid transformation, the pre-image and the image are congruent

Answer 2

The pre-image will be congruent to the image : True

Explanation:

The transformation falls broadly into two types.

Rigid Transformation and Non Rigid Transformation .

Rigid Transformation: The new image has the same size and the shape as that of pre image. Thus both the images are congruent to each other.

Non Rigid Transformation : The new image is has the same shape. however the size of the new image changes. hence they are similar to each other but not congruent.

Hence our third option is correct.
