5.3a Determining the image of an object under the combination of two isometric transformations
1. Translations, reflections and rotations are isometric transformations.
2. In an isometric transformation, the shape and the size of the image is the same as the object.
3. For two transformations, A and B,
(a) Combined transformation AB represents transformation B followed by transformation A.
(b) Combined transformation BA represents transformation A followed by transformation B.
(c) Combined transformation A2 = AA represents transformation A which is carried out twice consecutively.
