Question

The smaller triangle is the image of the larger triangle after a dilation. The center of the dilation is (4,2). What is the scale factor used to create the dilation?

Answer 1

I just took the test and got it correct!!

Step-by-step explanation:

Look at the image down below ♡＼(￣▽￣)／♡

Answer 2

Small triangle: The side // x axis has a length of 4
Large triangle: The side // x axis has a length of 12

So Small/Large = 4/12 = 1/3

Small triangle: The side // y axis has a length of 3
Large triangle: The side // y axis has a length of 9


So Small/Large = 3/9 = 1/3

So the scale factor to obtain this dilatation is 1/3
