Question

The graph below shows a transformation of the shaded rectangle onto the unshaded rectangle. Keesha says the transformation is a translation, but Teagan says that the transformation is a dilation. Which statement about the transformation is true?

A. Keesha is correct because the shaded rectangle is moved vertically to make the unshaded rectangle.
B. Keesha is correct because the shaded rectangle is flipped across a horizontal line.
C. Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle.
D. Teagan is correct because the unshaded rectangle is turned in a clockwise direction.

Answer 1

Size of the rectangle is changed, so it cannot be a translation.

This is a dilation, so Teagan is correct.

C. Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle.

Answer 2

Option C

Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle

Explanation:

we know that

In a translation the dimensions of the figure do not present changes

In this problem the unshaded rectangle represent a reduction of the shaded rectangle

therefore

Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle
