A triangle with vertices at A(0, 0), B(0, 4), and C(6, 0) is dilated to yield a triangle with vertices at A′(0, 0), B′(0, 10), and C′(15, 0)-. The origin is the center of dilation. What is the scale factor of the dilation?
A triangle ABC is similar to a triangle A´B´C´ The scale factor of the dilatation : s. 0 * s =0 4 * s = 10 6 * s = 15 s= 10/4=15/6=2.5 The scale factor of the dilatation is 2.5. It is shown in the attachment.
