| similar figures | Figures that have the same size but not necessarily the same size. |
| corresponding angles | Matching angles of two similar figures. |
| corresponing sides | Matching sides of two similar figures. |
| indirect measurement | Using similar figures to find a missing measurement that is difficult to find directly. |

| scale | A ratio that compares the measurements of a drawing of model to the actual measurements. |
| scale factor | A scale without units. |
| transformation | Changing a figure into another figure. |
| image | The new figure formed by a transformation |
| translation | A transformation in which a figure slides but does not turn. |
| reflection | A transformation in which a figure flips over a line called the line of reflection. |
| line of reflection | A line that a figure is flipped across to create a mirror image of the original figure. |
| rotation | A transformation in which a figure turns around a point called the center of rotation. |
