| cross products | in the proportion a/b = c/d, where b is not 0 and d is not 0, the cross products are ad and bc. The proportion is true if and only if the cross products are equal. |
| extremes | In a/b = c/d, the numbers a and d |
| fractal | A figure generated by repeating a special sequence of steps infinitely often. They often exhibit self-similarity. |
| iteration | A process of repeating the same procedure over and over again. |
| means | In a/b = c/d, the numbers b anc c |
| midsegment | A segment with endpoints that are the midpoints of two sides of a triangle |
| proportion | An equation of the form a/b = c/d that states that two ratios are equal. |
| ratio | A comparison of two quantities |
| scale factor | The ratio of the lengths of two correspoinding sides of two similar polygons or two similar solids |
| self-similar | When any parts of a fractal image are replicas of the entire image. |
| similar polygons | Two polygons having corresponding angles that are congruent and the measures of their corresponding sides are proportional. |
