Across
- 2. parts Points, sides, edges, or angles in two or more figures that are images of each other with respect to a sequence of transformations
- 3. compares two quantities by division
- 5. equation equation stating that two ratios are equal
- 8. factor The amount each side of a figure is multiplied by when the figure is proportionally enlarged or reduced in size
- 10. ~ If two triangles have all three pairs of corresponding sides that are proportional then the triangles are similar.
- 12. transformation that preserves the size, shape, and orientation of a figure while sliding it to a new location
- 13. figures Two shapes are similar if there is a sequence of rigid motions, followed by a dilation, that carries one onto the other
- 14. If two angles of one triangle are congruent to the two corresponding angles of another triangle, then the triangles are similar
- 16. transformations Movements of figures that preserve their shape, but not necessarily their size
- 18. Distance around the exterior of a figure on a flat surface
- 19. A transformation which produces a figure similar to the original by proportionally shrinking or stretching the figure
- 21. formed by two rays that are joined at a common endpoint
Down
- 1. a way that two objects are connected
- 4. Two shapes are congruent if there is a sequence of rigid transformations that carries one onto the other.
- 6. statement statement that indicates that two figures are similar

- 9. “If …, then …”
- 11. ~ If two triangles have two pairs of corresponding sides that are proportional and have congruent included angles, then the triangles are similar.
- 15. The longest side of a right triangle
- 17. a point where two or more line segments or rays meet to form a “corner,” such as in a polygon or angle.
- 20. argument logical sequence of statements and reasons that lead to a conclusion
