Question

Quadrilateral ABCD is dilated about the origin into quadrilateral EFGH

so that point G is located at (16, 8).
What is the scale factor? The original coordinate 8,4

Answer 1

The scale factor = 2.

Explanation:

The scale factor is the distance of G from the original divided by the distance of C from the origin.

= √(16^2 + 8^2 - 0) / √(8^2 - 4^2) = 0)

= √(192) / √(48)

= 2.

Answer 2

2

Explanation:

8 x 2 = 16

4 x 2 = 8
