Transformations are changes  in position or

orientation of a figure.  Types of transformations

include translations - slides along a straight line,

reflections - flips over a line of reflection, rotations -

turns on a fixed point.

scale factor

dilations

coordinates

Dilations are  transformations that change the size

but not the shape.  This is done by multiplying

the coordinates of each point by the same number. 

This number is called a scale factor.

 

Changes is size but not shape are called

scale factor

dilations

coordinates

Dilations are  transformations that change the size

but not the shape.  This is done by multiplying

the coordinates of each point by the same number. 

This number is called a scale factor.

 

The number each coordinate is multiplied by is

called a(n)

Reflection

When a shape is reflected across the "x" axis it is an

 up and down change.  This changes which number

in the ordered pair?

the "x" numbers

the"y" numbers

When a shape is reflected across the "y" axis it is a sideways

 change.  This changes which number in the ordered

pair?

the "x" numbers

the"y" numbers
