Across
- 2. If two angles of one triangle are congruent to two angles of another, then the triangles are similar
- 5. figures that have the same shape but not necessarily the same size (2 words)
- 6. a dilation with a scale factor between 0 and 1
- 8. (theorem) If two or more lines parallel to side of a triangle intersect the other two sides of the triangle, then they divide them proportionally (2 words)

- 13. the transformed figure
- 14. (theorem) If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally (2 words)
Down
- 1. the ratio of any two corresponding lengths in two similar geometric figures (2 words)
