# Geometry:Representing Transformations in a Plane

**Question description**

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?
