In this lesson you’ll learn about the concepts and procedure of performing the
basics of transformations. The presentation covering such content will be done
by the instructor in own handwriting, using video and with the help of several
examples with solution. This will help you understand important geometry
transformations and how to make use of them.
In common and simple language: Rotation means Turn using center of shape or certain point,
Translation
means slide, Dilation means enlargement or reduction and Reflection means
Flip over x or y axis.
A transformation is thus a copy of a geometric figure, where preimage and image
have common properties i.e. a correspondence between two sets of points such
that each point in the preimage has a unique image and that each point in
the image has exactly one preimage (Fig1:below):
