|---|---|---|---|---|---|
| angle of rotation | the angle formed by rays drawn from center of rotation to a point and its image
🗑
|
||||
| center of rotation | see rotation
🗑
|
||||
| center of symmetry | see rotational symmetry
🗑
|
||||
| component form | the form of a vector that combines the horizontal and vertical components of a vector
🗑
|
||||
| composition of transformation | the result when two or more transformations are combined to produce a single transformation
🗑
|
||||
| dimensions | the number of rows and columns in the matrix; if matrix row has m rows and n columns, the dimensions of the matrix are m x n
🗑
|
||||
| element | a number in a matrix
🗑
|
||||
| glide reflection | a transformation in which every point P is mapped to a point P"by the following steps; (1) A translation maps P to P'; (2) A reflection in a line k parallel to the direction of the translation maps P' to P"
🗑
|
||||
| horizontal component | the horizontal change from the initial point to the terminal point of a vector
🗑
|
||||
| image | the new figure that is produced in a transformation
🗑
|
||||
| initial point | the starting point of a vector
🗑
|
||||
| isometry | a transformation that preserves length and angle measure
🗑
|
||||
| line of reflection | see reflection
🗑
|
||||
| line of symmetry | see line symmetry
🗑
|
||||
| line symmetry | a figure in the plane has line symmetry if the figure can be mapped onto itself by a reflection in a line; this line of reflection is a line of symmetry
🗑
|
||||
| matrix | a rectangular arrangement of numbers in rows in columns
🗑
|
||||
| preimage | the original figure in a transformation
🗑
|
||||
| rotational symmetry | a figure in the plane has rotational symmetry if the figure an be mapped onto itself by a rotation of 180 degrees or less about the center of the figure; this point is the center of symmetry
🗑
|
||||
| scalar multiplication | the process of multiplying each element of a matrix by a real number or scalar
🗑
|
||||
| terminal point | the ending point of a vector
🗑
|
||||
| vector | a quantity that has both direction and magnitude, and is represented in the coordinate plane by an arrow drawn from one point to another
🗑
|
||||
| vertical component | the vertical change from the initial point to the terminal point of a vector
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
