The result of moving a shape according to a rule; translations, reflections, and rotations are all ways to transform shapes.
Perform a single transformation (translation, rotation or reflection) of a 2-D shape, and draw and describe the image. Identify and describe a single transformation, including a translation, rotation and reflection of 2-D shapes.
The result of sliding a shape along a straight line. Translation Rule: A way of describing a translation with pictures or numbers. Ex: 2 units left, 2 units up
the 2-D shape and its image are congruent (size and shape are the same) the 2-D shape and its image have the same orientation (that is, if we go around the object ABCD in a clockwise direction, we should be able to also go around its image A'B'C'D' in a clockwise direction.)
- a 2-D shape and its image are congruent - a 2-D shape and its image are of opposite orientation (This is, if we go around the object ABCD in a clockwise direction, the image A'B'C'D‘ would require a counter-clockwise direction.)
The result of turning a shape. Center of Rotation: The point that a shape turns around Clockwise (cw): The direction a clock’s hands move. Counterclockwise (ccw): The opposite direction to clockwise. Orientation: When the orientation of a shape changes, the vertices of the shape will be in a different order.
