Term | Definition |
---|---|
Line of Symmetry | a line or fold in the image where the two halves match exactly |
Reflection | a transformation representing a flip of a figure |
Isometry | when the figure does not change size after a transformation. The preimage and image are congruent. All sides and angle measures are preserved. |
Rotation | a transformation that turns every point of the preimage through a specified angle and direction about a fixed point called the center of rotation |
Transformation | maps an initial figure called a preimage onto a final figure called an image (translation, rotation,reflection) |
Translation | a transformation that moves all points of a figure the same distance in the same direction. |
Line of Reflection | a shared line of symmetry between the preimage and image |
Angle of Rotation | Determined by angle formed at center of rotation to a point on the preimage and the corresponding point on the image |
