A transformation is a function done to X, it can be: moving X, enlarging X,
reflecting X or rotating X, but preserves X's structure. In maths X is usually a
2d shape and we show the transformation on a graph or grid, this allows us to
accurately explain where certain points are like mirror line x=3. For each
transformation to make sense you have to give a number of details depending
on the transformation, like the centre point or is clockwise or anti-clock wise.…read more

Scaling is a transformation that enlarges or reduces objects; the scale factor is
the same in all directions. If you have a negative scale factor the gets moved
to the other side ( almost like a rotation in some cases). The result of scaling
is similar (in the geometric sense) to the original. In order to perform a full
enlargement you need to know certain data:
· The scale factor
· The centre
Centre…read more

Reflecting is a transformation that reflects a shape about a mirror line. The
reflected image is reflected onto the other side of the mirror line. For example
a vertical reflection of the letter p is q. There is a certain data needed to
perform a reflection:
· You need the equation of the mirror line (e.g. x=9)…read more

A translation is a transformation that moves every single point on the object in
the same manner. The manner by which the object is moved is recorded in the
form of a vector. The vector looks something like this (x/y) where x is the
amount you move to the right ( negative if left) and y is the amount you move
up (negative if down). This is the only data you need perform a translation.
