Across
- 3. The quantity relationship between two amounts showing the number of times one value contains or is contained within the other.
- 6. When part of an original figure, matches of with a part of the copy. These could be points, segments, angles, or distances.
- 7. term It doesn't change when "x" changes.
- 13. A transformation in which each point on a figure moves along a line and changes its distance from a fixed point.
- 14. A number we can calculate using any two points on the line
- 17. If there is a positive K so that the quantities X and Y are related by the equation y=kx, then we say that y and x are in a proportional relationship, and that y is proportional to x.
- 20. to turn opposite of the way the hands of a clock turn
- 23. In the coordinate plane the origin is point (0,0)
- 25. A reflection across a line moves every point on a figure to a point directly on the opposite side of the line.
- 26. Two ratios a:b and c:d are equivalent if there is a number that you can multiply both a and b to get c and d.
- 27. The horizontal number line (x axis) and the vertical number line (y axis) that intercepts at the origin (0,0)
- 28. intercept The point where the graph of a line crosses the vertical axis
Down
- 1. The factor by which every length in an original figure is increased or decreased when making a scale copy
- 2. If one can fit exactly over the other after rigid transformations and dilations
- 4. A fixed point on a plane. It is the starting point from which we measure distances in a dilation.
- 5. Moving every point, on a figure around a center by a given angle, in a specific direction
- 8. A linear relationship is the amount "y" changes when "x" increases by 1.
- 9. The number that is the constant proportionality between the circumference, or a circle, and its diameter
- 10. the distance from eh center of the circle to any point on the circle. The corresponding line segment from the center to a point on a circle.
- 11. A move that does not change any measurements of a figure.
- 12. It moves every point in a figure at a given distance, in a given direction
- 13. a line segment that has endpoints on a circle and passes through the center.
- 14. angle An angle that forms a straight line
- 15. Two angles or arcs who sum is a 180 degrees
- 16. To turn in the same direction as the hands of a clock
- 18. angles Opposite angles that share the same vertex
- 19. If it can be moved which translations, rotations, and reflections to fit exactly over the other.
- 21. The result of translations, rotations, and reflections on an object
- 22. relationship When one quantity changes by a certain amount, the quantity always changes by a set amount
- 24. The distance around a circle
