Across
- 2. a midsegment of a triangle is parallel to one side of the triangle its length is one half the length of the side
- 3. if two angles of one triangle are congruent to two angles of another triangle then the two triangles are similar
- 4. if an angle of one triangle is congruent to an angle of another triangle and the lengths of the sides including these angles are proportional then the triangles are similar
- 5. compares three or more numbers
- 9. all lengths are proportional to their corresponding actual lengths
- 10. is the ratio that compares each length in the scale drawing to the actual lengths
- 14. a method of using proportions to find an unknown length in similar figures
- 15. the first and last numbers in a proportion
Down
- 1. must match corresponding angles and sides
- 6. an equation that states that two ratios are equal
- 7. is the ratio of corresponding linear measurements of two similar figures
- 8. if all three sets of corresponding side lengths of two triangles are proportional then the triangles are similar
- 11. have the same shape but not necessarily the same size
- 12. the middle two numbers in a proportion
- 13. is a comparison of two quantities by division you can write the ratio of two numbers a and b
