Question

Select the correct answer.

A triangle with vertices at A(0, 0), BIO, 4), and C16, 0) is dilated to yield a triangle with vertices at Ato, O), BIO, 10), and C[15, 0). The origin is the center of dilation. What is the
scale factor of the dilation?
OA 1.5
OB.
2
OC. 2.5
OD. 3

Answer 1

c. 2.5

Explanation:

4×2.5 => 10

6×2.5 => 15

so scale factor = 2.5
