Question

Quadrilateral A’ B’ C’ D’ is a dilation of quadrilateral ABCD about point P with a scale factor of 2 and a half .

Is the dilation a reduction or an enlargement?

reduction
enlargement

Answer 1

Answer: enlargement

Explanation:

A dilation is a transformation which stretches or shrinks the original shape.

It creates similar shapes but of different size.

If the scale factor is greater than 1 then the image is an a stretch or enlarged.

If the scale factor is between 0 and 1 then the image is a reduction or a shrink.

If the scale factor is 1 then the figure and the image are congruent.

The given scale factor is
`2(1)/(2)`

Since
`2(1)/(2)` >1 .

Therefore, the dilation is enlargement .

Answer 2

it is an enlargement because the scale factor is 2 and a half
