Every dilation has a

a)reduction and enlargement

b)reflection and rotation.

c)center and scale factor

d)translation and glide reflection.

Option: c is the correct answer.

Every dilation has a :

            c)  center and scale factor.

Dilation--

In mathematics, a dilation is a transformation that changes the size of the original figure while there is no change in the shape of the original figure.

The original figure either enlarges or shrinks depending on a factor known as a scale factor.

If the figure is larger in size as compared to the original figure then it is called enlargement and if it is of a smaller size then it is known as  reduction.

       It includes a scale factor and center of dilation.

Scale factor is a fixed number by which the size of the figure changes and center of dilation is a fixed point in the plane about which the dilation is done.

If scale factor>1 then figure enlarges.

If scale factor<1 then the figure shrinks or reduces

and if scale factor=1 then the size of the figure remains unchanged.
