unit 6 symmetry
math unit 6 symmetry
| Question | Answer |
|---|---|
| Asymmetrical | Describes any figure that cannot be divided into two parts that are mirror images of each other. In other words, asymmetrical means "not symmetrical." |
| Axis of Symmetry | |
| Line of Symmetry | |
| Line of Symmetry | A line that divides a figure into two parts, each of which is a mirror image of the other. |
| Reflectional Symmetry | A figure has reflectional symmetry if, after reflecting the figure over a line, the figure lines back up with itself |
| Rotation | A transformation that turns a figure about a fixed point at a given angle and a given direction. |
| Rotational Symmetry | A figure has rotational symmetry if, after rotating it by an angle of 180 degrees or less about its center, the figure lines back up with itself. |
| Symmetry | The property of a figure or expression that allows for parts of it to be interchanged without forcing a change in the whole |
| Axis of Symmetry | A line that a figure can be folded over so that one-half of the figure matches the other half perfectly; a line about which a figure is symmetrical. |
| Line Symmetry | Figures that match exactly when folded in half have line symmetry. |
