Triangle CAT has coordinates C (4,8) A (6,10) and T ( 6,4) where is A' after a dilation of scale factor of 1/2 

• (6,10)

• (3,2)

• (3,5)

• (0,0)

Why does the scale factor of "1" NOT result in a dilation?

• making an image 1 times larger would not change its size, therefore it would remain the same/congruent image

• 1 cannot be a scale factor because it is not a fraction

• 1 cannot be a scale factor because it is not a decimal
