3. The ratio of the length on the model or drawing to the actual length of the object being modeled or drawn
4. The product of the means and the product of the extremes
7. The ratio of the lengths of the corresponding sides of two similar polygons
8. If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar- Postulate 7.1
9. An equation stating that two ratios are equal
13. A comparison of two quantities using division
14. One of the Properties of similarity = If ∆ABC~∆DEF, and ∆DEF~∆XYZ, then ∆ABC~∆XYZ

5. One of the properties of similarity = ∆ABC~∆ABC
6. Theorum 7.2 - If the corresponding side lengths of two triangles are proportional, then the triangles are similar
10. an image that is smaller than the original figure
11. When a figure and it's transformation are similar

16. A segment with endpoints that are midpoints of two sides of the triangle
17. another word for scale model
19. The center point from which dilations are preformed
