Unit 1 Vocabulary

4. a rigid transformation in which a figure is flipped over a fixed line to create a mirror image.
10. the line of a graph that runs horizontally
11. a rigid transformation that turns every point on a figure around a center point in a specific direction and a specified amount
14. the measure of the amount that a figure is turned about a fixed point
16. a transformation in which the figure gets proportionally larger or smaller based on the scale factor
18. a figure that can be moved with a rigid transformation to fit exactly over the other
20. a fixed point about which a figure turns
21. a part of an original figure that matches up with a part of a copy
22. when the corresponding parts of 2 figures have the same ratio
24. a move that does not change any measurement of a figure
25. to turn in the opposite direction as the hand on a clock

1. a translation, reflection, rotation, dilation or combination of these
2. a set of two or more transformations performed in a given order on a figure
3. the line of a graph which a figure is flipped to create a mirror image
5. when one figure can fit exactly over another after a dilation
6. a fixed starting point from which we measure the distance in dilation
7. the ratio of any two corresponding measurements in two similar figure
8. the original figure before a rigid transformation
9. a rigid transformation that slides every point in a figure the same direction and distance
12. when one shape is identical to the other when it is moved (usually through a reflection); a shape tgat can fold on itself.
13. to turn in the opposite direction as the hands on the clock
15. the resulting figure after a rigid transformation
17. the point at which the x & y axis intersect; ordered pair (0,0)
19. to turn the same direction as the hands of a clock
23. the line of a graph that runs vertically
