1Translations I can: Vocabulary: Define and identify translations. Understand prime notation to describe an image after a translation.I can describe the changes occurring to the x and y coordinates of a figure after a translation.Vocabulary:TransformationsTranslationsCongruent FiguresParallel lines
2Transformationschange the position of a shape on a coordinate plane. *What that really means is that a shape is moving from one place to another.
3Translation (Slide) The action of sliding a figure in any direction. *We use an arrow to represent the direction of the slide.
4A translation does not need to be in a vertical or horizontal direction. It can also be in a diagonal direction.
5Translation on LinesThe size stays the same, the object is just slid to a new location.The lines are considered parallel lines- lines are parallel if they lie in the same plane, and are the same distance apart over their entire length.
6Translation on AnglesThe angle degree stays the same, the angle is just slid to a new location.
9Reflections I can: Vocabulary: Define and identify reflections. Understand prime notation to describe an image after reflection.Identify lines of reflection.I can describe the changes occurring to the x and y coordinates of a figure after a reflection.Vocabulary:ReflectionsLine of ReflectionLine of Symmetry
10Reflection (Flip)A transformation representing a flip of a figure over a point, line, or plane.
11A reflection creates a mirror image of the original figure. The original figure and its image are congruent.
12Line of ReflectionA line in which you reflect a figure over.
13Line of SymmetryA line that can be drawn through a plane figure so that the figure on one side is the reflection image of the figure on the opposite side.
14Reflection of LinesThe size stays the same, the object is just the mirror image of itself.
15Reflection of AnglesThe angle degree stays the same, the angle is just the mirror image of the original angle.
17Coordinate PlaneA reflection across the y-axis RULE: (x, y) (-x, y)
18Coordinate PlaneA reflection across the x-axis RULE: (x, y) (x, -y)
19Rotations I can: Vocabulary: Define and identify rotations. Identify corresponding sides.Understand prime notation to describe an image after a rotation.Identify center of rotation.Identify direction and degrees of a rotation.Vocabulary:RotationsAngle of RotationCenter of Rotation
20Rotations (Turns)A transformation in which a figure is rotated about a point called the center of rotation.
21Angle of Rotation The number of degrees a figure rotates. 90 Degree Turn
22Center of RotationThe point in which a figure is rotated.
25Same length; rotated 90 degrees clockwise Lines are not parallel Rotations of LinesA line that rotates remains the same length, but will not necessarily remain parallel.Same length; rotated 90 degrees clockwise Lines are not parallel
26Same degree measure; rotated 90 degrees counter-clockwise Rotations of AnglesAngles that are rotated will remain the same degree measure.Same degree measure; rotated 90 degrees counter-clockwise
