what is translation, rotation and reflection
Plane figures and solids can be changed (or transformed) by translation, reflection and dilation. The symmetry of shapes is related to translation, reflection and rotation. Triangle ABC and its reflection A'B'C' have the same size and shape, that is they are congruent. A translation is defined by specifying the distance and the direction of a movement. For example, triangle ABC is translated by 2 units to the right. Triangle ABC and its image A'B'C' have the same size and shape.
â¢ A rotation is an isometry where all points in the. preimage are moved along circular arcs. determined by the center of rotation and the. angle of rotation. â¢ A rotation may also be called a turn. â¢ This transformation can be more complex than a. translation or reflection because the image is.
Reflection Symmetry. The simplest symmetry is Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry). It is easy to see, because one half is the reflection of the other half. of photo magic. it is not perfect symmetry, as the image is changed a little by the lake surface.
