Across
- 1. if the corr. lengths of 2 triangles are proportional then the triangles are similar
- 4. if 3 or more parallel lines intersect 2 transversals then they cut off the transversals proportionally
- 6. if a line parallel to a side of a triangle intersects the other two sides, then it divides those sides proportionally
- 8. in a proportion, the product of the extremes is equal to the product of the means
- 9. comparison of 2 quantities using division
- 11. the segment connecting the midpoints of two sides of a triangle is parallel to the third side and is half as long
- 12. the ratio of the corr. sides of 2 similar polygons
- 14. a segment that joins the midpoints of 2 sides of a triangle
- 15. if 2 sides of 1 triangle are proportional to 2 sides of another triangle and the included <‘s are congruent then the triangles are similar
Down
- 1. identifies all the corr. parts
- 2. if 2 polygons are similar, then their perimeters are proportional to the scale factor between them
- 3. comparison of 3 or more quantities
- 5. equation that states 2 ratios are equal
- 7. if a line divides two sides of a triangle proportionally, then it is parallel to the third side
- 10. if if 3 or more parallel lines cut off congruent segments on 1 transversal then they cut off congruent segments on all transversals
- 13. if 2 <‘s of 1 triangle are congruent to 2 <‘s of another triangle then the triangles are similar
