Similarity and Transformations
WHAT IS IT AND HOW DO YOU FIGURE IT OUT?
What is similarity?
But that's always the case. Two figures can be similar if the second can be obtained by a number of transformations and dilation.Here is a simple picture of classification. you can easily classify then by their shape, size, and color.But can you classify them by their angles and vertices and more?
Moving a shape, without rotating or flipping it. You bascially are just sliding over the plane.
Reflection means when the figure is the mirror image of the other on a coordinate plane. Here is the a to the left.
Dilation means to increase in size from its original shape size.
" Step 1 "
AB = 2 1. AC = 3
------ ~or ~ ------ ~ but this pair isn't equal so it doesn't count. (AC=A'C')
A'B'= 4 2. A'C'= 5 .
There is no need to do CB and C'B' because its equal to AB A'B'C'. So now knowing that you know the 2 images are similar because a dilation maps ^ABC to ^A'B'C' . So that's how you figure out similarity by using transformations. Hope you learned something new :)
