Vocab Terms for Modules 5-6
Across
- 3. a figure that can be rotated about its center by an angle of 180 degrees or less so that the image coincides with the preimage
- 5. the fixed point in the plane that does not change when the dilation is applied
- 8. something that maps a transformation
- 9. changes the shape of a figure by factor greater than 1 in one direction
- 12. changes the shape of a figure by a factor greater than 0 and less than 1 in one direction
- 14. a quantity that has both direction and magnitude
- 15. changes the size of a figure by the same amount in all directions
- 16. a transformation that maps the figure to itself
- 17. a rigid motion that turns a figure through an angle of rotation about a point and its image that are the same distance from a point
- 18. divides a plane figure into two congruent, reflected halves
Down
- 1. a function that changes the position, size, or shape of a figure or graph
- 2. a transformation that does not change the size or shape of a figure
- 4. the perpendicular bisector of each segment joining each point and its image
- 6. the smallest angle of rotation that maps a figure to itself
- 7. has this if it can be reflected over a line so that the image coincides with the preimage
- 10. used when translating a figure in a coordinate plane
- 11. a transformation that maps every point of a figure or graph the same distance in the same direction
- 13. determined by set of points in the plane to a corresponding set of points
- 17. a transformation across a line
