Transformation in Geometry

Transformation: 

At assembly we presented our three charts that we all contributed to to demonstrate the key idea of transformation. At level 1 is that the position and appearance of an object can be changed by reflecting (flipping), translating (sliding) and rotating (turning) it. At level 1 students understand that objects can be moved in space.  Together as a class we have completed our Geometry unit with revision of Stage 1.

Reflections (flip). Objects can be reflected or flipped through lines which are external (outside) to the shape, or which run through the shape. Objects which have been reflected are described as mirror images of the original object. 

  Rotations (turn): Objects are turned in a circular motion around a fixed point, which is called the centre of rotation. The centre of rotation can be inside or outside the shape itself. The amount the object is turned is called the angle of rotation. 

Translations (slide). Objects that have been moved by translation, or sliding, look the same as the original object, but they are in a different position.
