| rotation | A turn of a figure around a fixed point. |
| center of rotation | the point from where a rotation begins |
| image | the figure resulting from a transformation |
| rotational symmetry | when a figure can be rotated less than 360 degrees about its center and fit exactly on itself |
| rotational symmetries | the numbers of degrees less than 360 that a figure can be rotated and fit exactly on itself |
| vertex of a triangle | the point wher two sides of a triangle meet |
| congruent | Two figures that are the same shape and the same size |
