2. the new figure that is produced in a transformation.
4. a transformation that preserves length and angle measure.
5. the original figure in a transformation.
8. the form of a vector that combines the horizontal and vertical components of the vector.
9. the process of multiplying each element of a matrix by a real number.
10. a figure in the plane has rotational symmetry if the figure can be mapped onto itself bu a rotation of 180 degrees or less about the center of the figure.
14. the line that an object is reflected over.
15. the point at which an object rotates around.
16. a transformation in which every point P is mapped to a point P" by the following steps.

1. a rectangular arrangement of numbers in rows and columns.
3. a figure in the plane has line symmetry if the figure can be mapped onto itself by a reflection in a line.
6. a quantity that has bot direction and magnitude, and is represented in the coordinate plane by an arrow drawn from one point to another.
7. the result when two or more transformations are combined to produce a single transformation.
11. a number in a matrix.
12. the angle formed by rays drawn from the center of rotation to a point and its image.
13. the numbers of rows and columns in the matrix.
