DESCRIPTION
M. Wilkes & D. Smith 3 rd period 3.25.2013. What properties of a figure are preserved under a translation, reflection, or rotation?. Translation Page 1. A translation is a transformation of the plane that slides every point of a figure the same distance in the same direction. - PowerPoint PPT PresentationTRANSCRIPT
A translation is a transformation of the plane that slides every point of a figure the same distance in the same direction.
A translation is a direct isometry. A translation creates a figure that is
congruent with the original figure
Translations may be combined with rotations and reflections.
A translation is the same as sliding/shifting an object.
The original object and its image are congruent - identical in every respect except for their position.
A transformation where each point in a shape appears at an equal distance on the opposite side of a given line
A mirror image Has the same size of the original image
The operation of exchanging all points of a mathematical object with their mirror images
They flip in a 180 degree angle
Turning around a center The distance from the shape stays
the same Every point makes a circle around
the center
the turning of a body part about its long axis as if on a pivot
rotation is a transformation in a plane or in space that describes the motion of a rigid body around a fixed point
We learned: That transformations can be used in many ways. Like real life situations such as: art, geometry, and graphic designs We had a little difficulty: We didn’t have any difficulty with nothing.The easiest part of the lesson was: Finding the pictures for the transformationsWe enjoyed: Doing the whole projectWe would like to: Learn something different
