... If we were to consider plotting ∆ABC on a Cartesian plane, we could consider ∆ ABC to be the image of a similarity transformation of ∆ABC. A similarity transformation of a Euclidean space is a function from the space into itself that multiplies all distances by the same scalar (Wikipedia, 2005). ...

... Similar geometric figures can be created by transformations. All transformations create similar geometric figures. Dilations, in particular create figures that are similar, but may not be congruent. The processes of proving include a variety of activities, such as developing conjectures, considering ...
