To find the scale factor, divide the corresponding side lengths of the image triangle by the corresponding side lengths of the preimage triangle.
For the first side, 35/10 = 3.5
For the second side, 49/14 = 3.5
For the third side, 56/16 = 3.5
Therefore, the scale factor of the dilation is 3.5.
The side lengths of triangle ABC are 10, 14, and 16. The side lengths of triangle A′B′C′ are 35, 49, and 56. Identify the scale factor of a single dilation between the preimage ABC and image A′B′C′.(1 point)
