... Dilations and Similarity in the Coordinate Plane A dilation is a transformation that changes the size of a figure but not its shape. The preimage and image are always similar. A scale factor describes how much a figure is enlarged or reduced. ABC Triangle ABC has vertices A(0, 0), B(2, 6), and A ...

... Extend the edge AB to some point D and the edge AC to some point E (Postulate 2). Choose an arbitrary point F on the segment BD (what allows us to do this—I’m not sure). Find the point G on AE such that the length of AG equals the length of AF (Proposition I.3). (Here we assumed that AE was long eno ...

... Suppose that A inverts the order of the vertices, that is, A(vi ) = vt+n−1−i for all i = 0, 1, . . . , n−1. Then, either the operator A′ such that A′ (Vet ) = Ve2t , or the operator A′ A (for which, obviously, A′ A(Ve0 ) = Ve2t ) preserves the order of the vertices. Therefore we may assume that A p ...
