chapter 7 vocab

2. / A transformation that turns every point of a pre image. The pre image is a specified angle and direction about a fixed point
5. / you can move the entire design by either rotation, reflection, or translation, and the design appears unchanged.
8. /a transformation that moves all points of a figure. the points move all in the same distance in the same direction
10. /a line that passes through two other lines. the two other lines are parallel to each other.
11. / a composition of a translation and a reflection. on a parallel line it moves to the direction of the translation
12. / A transformation that is congruent
14. / the line that is equidistant from the preimage and image points
15. /The ratio of a length on an image to a corresponding length on the pre image.

1. / transformation that preserves distance and angle measure. Reflections, rotations, translations, and glide reflections are all examples
3. / The figure after the transformation
4. / exists when a figure is built around a single point called the center of the figure
6. /an object that looks the same after a certain amount of rotation
7. / has the same or opposite direction
9. / The original figure
13. / The point from which dilations are performed.
15. /The ratio of the lengths of two corresponding sides. it has two similar polygons or two similar solids.
16. /a plane, mapping for which each point has exactly one image. each image point has exactly one pre image point. change in position, size or shape of a geometric figure
17. /A transformation representing a flip of the figure over a point
18. / A transformation determined by a center point. a figure by reducing or enlarging it with a scale factor
19. / A line that can be drawn through a plane . a figure that can be the reflection image of the figure on the opposite side
