Question

Given the triangle ABC with the points A = (-1,3 ) B = (2, 4) C= (4, 7) and it's dilation, triangle A'B'C', with points A' = ( - 3, 9) B' = (6,12) C' = (12, 21 ) what is the scale factor?

Answer 1

Given the points of triangle ABC:

A = (-1, 3)

B = (2, 4)

C = (4. 7)

Let's determine scale factor in getting the following points of triangle A'B'C'.

A' =
