Question

The smaller triangle is the image of the larger triangle after a dilation. The center of the dilation is (−3,−2).

What is the scale factor used to create the dilation?

Enter your answer in the box.

Answer 1

The scale factor is -1/4.

Answer 2

-1/4

Explanation:

The smaller triangle is the image of the larger triangle after a dilation. The center of the dilation is (−3,−2).

The length of the base of larger triangle is 8 units

The base is reflected with center (-3,-2). the length becomes 2 units

The length of larger triangle is 8 units . the length of smaller triangle is 2 units.

8 unit becomes 2 units

LEt scale factor = x

8* x = 2

`x= (2)/(8) =(1)/(4)`

Length is decreased

So scale factor =
`(-1)/(4)`
