If triangle abc is dilated by a scale factor of 2 with a center of dilation at vertex c, how does the perimeter of a'b'c' compare with the perimeter of abc? a) the perimeter of a'b'c' is 2 times the perimeter of abc. b) the perimeter of a'b'c' is 4 times the perimeter of abc. c) the perimeter of a'b'c' is 6 times the perimeter of abc. d) the perimeter of a'b'c' is 8 times the perimeter of abc.

Scaling triangle ABC with a scale factor of 2 will result in the image A'B'C' having sides which are twice the size of the sides of ABC.

Let the size of the sides of ABC be x, y and z, then the perimeter of ABC is x + y + z.
Dilation of ABC with a scale factor of 2 will result in the image A'B'C' with sides, 2x, 2y, and 2z, with perimeter 2x + 2y + 2z = 2(x + y + z) = 2 times the perimeter of ABC.
