Question

Dilation D was performed on a rectangle. How does the image relate to the pre-image? Select three options.

Vies
The image is a reduction because 0 The side lengths of the image are two-fifths the size of the corresponding side lengths of the pre-image.
The angles of the image are two-fifths the size of the angles of the pre-image.
The center of dilation is at point Q.
The base of the image is two-fifths the size of the base of the pre-image.

Answer 1

A,B and E

Explanation:

Dilation = was done on a rectangle.

→As Factor of Dilation is 0.4, which is less than 1.

→So, the image will be smaller in size than Pre image.

→As, the two rectangles , Pre image and image are similar so their sides will be proportional.

As in similar figures the interior angles are congruent.

As the images are similar , so Base of the image will be two fifths of the size of the base of preimage.

Option A,B and E are Correct.

A: The image is a reduction because n < 1.

B : The side lengths of the image are two-fifths the size of the corresponding side lengths of the pre-image.

E. The base of the image is two-fifths the size of the base of the pre-image.
