| Term | Definition |
|---|---|
| Composition of rigid motion | is a transformation with two or more rigid motion and which the second region motion is performed on the image of the first rated motion |
| Glide reflection | is the composition of a reflection followed by a translation in a Direction parallel to the line of reflection |
| Perpendicular bisector | a segment is a line segment or Ray that is perpendicular to the segment and divided the segment into two congruent segments |
| Point symmetry | the type of symmetry for which there is a rotation of 180 that Maps a figure onto itself |
| Reflection | across line X called the line of reflection is a transformation such that if a point a is on the line x then the image of a is itself. |
| Reflectional symmetry | symmetry for which there is a reflection that Maps a figure onto itself that implement is the line of symmetry the line of symmetry divides a figure into two congruent halves |
| Rigid motion | Is a transformation that preserves distance and angle measures a rigid motion is sometimes called a congruence transformation |
| Rotation | X about A point or called the center of rotation. The positive number of degrees X that a figure rotates is the angle of rotation. |
| Rotational symmetry | Is the type of symmetry for which there is a rotation of 360 or less that maps a figure onto itself |
| Symmetry | A figure has symmetry if there is a rigid motion that Maps the figure on two itself |
| Transformation | is a change in the position size or shape of a geometric figure |
| Translation | moves points to the same distance and the same direction a translation is a rigid motion |
