3. Use the definition of dilation to describe
the lengths along this ray.
1. On the first line of your paper, mark a
point . We will use this as our center.
From point O, draw a ray OP.
Mark the point P a few lines down from the center.
Now, choose a P' farther down the ray, also on one of
the lines of the notebook paper. For example, you
may have placed point P, 3 lines down from the
center, and point P', 5 lines down from the center.
