Question

Which statements are true about dilations? Select all that apply.

Answer 1

A, C, and E. This is because dilations change the size/length of the sides = the sides cannot be congruent, however the angles are the same.

Answer 2

Answer with explanation:

Dilation of any geometrical shape means, producing an image , that has larger or smaller size than Pre image,

→Image > Pre-Image,≡If dilation factor > 1

→Image < PreImage,≡If 0<Dilation factor<1.

But , Image and Preimage are Similar in both the cases.

So,out of the five statement, the correct statements are:

1. Dilations produce images that are similar to the pre-image.

3. Dilations produce images that have angles that are congruent to the pre-image.

5. Dilations produce images that have sides that are proportional to the pre-image.
