1. when an object moves but maintains its shape and size
5. The imaginary line across which a shape is reflected to create its mirror image
7. a reference point used to appropriately scale the dilation of a figure
8. expand the size of only ONE of the coordinates
9. The new (transformed) shapes
10. the image of a graph or shape before it is taken through a transformation
12. when an object is rotated on its own axis, the shape of the object looks the same
14. the shifting of a figure from one place to another without rotating, reflecting or changing its size
16. a geometric transformation that consists of a reflection across a hyperplane and a translation ("glide") in a direction parallel to that hyperplane, combined into a single transformation
19. the measure of the amount that a figure is rotated about a fixed point called a point of rotation
22. A compression occurs when a mathematical object is scaled by a scale factor less in absolute value than one
23. an object that has both a magnitude and a direction
24. the ordered pair that describes the changes in the x- and y-values

2. changing a shape's position or which way the shape points
3. a line that cuts a shape exactly in half
4. two or more transformations performed consecutively on the same figure
6. the smallest angle the figure can be turned to make it look the same as it originally did
11. the circular movement of an object around a centre
13. a mirror image of the shape
15. a balanced and proportionate similarity that is found in two halves of an object
17. he rigid transformation of an object or image on a plane
18. the point at which a picture turns
20. a line that cuts a shape exactly in half.
21. a ratio between two corresponding sides of similar shapes
