Lesson: Dilations on the Coordinate Plane
In this lesson, we will learn how to find the coordinates of the vertices of an image after dilation given the scale factor by using origin-centered dilation.

Dilate triangle from the origin by a scale factor of 2, and state the coordinates of the image.
Triangle has been dilated from point to triangle and, hence, the two triangles must be similar. What do you notice about the measures of the angles in both shapes?
Describe the single transformation that would map onto .
Hence, determine whether triangles and are similar.
