Transformations are an act of transforming the figure, so its size, orientation, or location changes. Symmetry is visual balance in designs or shapes. The concepts learned in this unit are:
Rotation is the act of rotating a figure around a point. It changes the orientation and location of the figure. Architecture uses rotations when trying to increase interest and ingenuity in the structure.
Dilation is the act of changing the size of a figure according to a scale factor around a point. It increases or decreases the figure. This is a key element in Architecture because it is hand in hand with proportions and when building the actual structure.
Reflection is when you flip the figure over a line. It changes the orientation and location of the figure. In Architecture, it is used to create symmetry, which ensures balance of the structure.
Translation is moving the figure according to the vector, which is the key to how much the figure is moved and in what direction it is moved. It is used in Architecture, when architects move a certain figure to a different location to get unity in the structure.
