Exercise 4 Page 81

Is there a combination of dilations and rigid motions that maps one figure onto the other?

Yes.

Practice makes perfect

Let's start by drawing the figures. To do so, we will plot and connect the given vertices.

figures

It appears as though these figures may be similar. Let's try to find a sequence of dilations that maps one figure onto the other.

figures

We found a sequence of dilations that maps one figure onto the other. Therefore, the figures represent a scale drawing.
