Marking a Ratio Using Two Segments

1.  Select a segment whose length will be used as the numerator of your ratio.

2.  Select a second segment whose length will be used as the denominator.

3.  Choose Mark Segment Ratio from the Transform menu.

You can also mark a segment ratio after choosing Dilate. With the Dilate dialog box open, click on the first and then the second segment in your sketch.

You will see a brief animation confirming that the ratio has been marked.

If the first segment is shorter than the second, the ratio is less than 1 and dilation will shrink objects toward the marked center. If the first segment is longer than the second, the ratio is greater than 1 and dilation will stretch objects away from the marked center.
