Scaling changes the size of a figure.
If the scale factor is greater than 1, the figure is enlarged;
if the scale factor is less than 1, the figure is reduced.
I the scale factor is equal to 1, the figure's size is unchanged.
If there is a centre of enlargement, the new figure can be drawn exactly by multiplying the distance of every point from the centre of enlargement, multiplying this by the scale factor and drawing the new point at this distance from the centre of enlargement. (For a polygonal figure, only the vertices need be measured and the lines between the vertices of the original figure drawn in).
With a centre of enlargement, the scale factor can be negative. In this case, the distance to the new points is measured on the opposite side of the centre to the original points, so that it is a straight line form the original point, through the centre to the new point.

What is the transformation that reduces or enlarges a figure?
congruent figure
What is a ratio that enlarges or reduces similar fractions?
scale model
A figure resulting from a transformation?
A figure resulting from a transformation is called an IMAGE
A transformation that proportionally reduces or enlarges a figure?
Scaling will proportionally reduce or enlarge a figure. The amount of scaling is given by the scale factor (greater than zero) If the scale factor is less than 1, the figure is reduced and it is sometimes called a contraction If the scale factor is greater than 1, the figure is enlarged, and it is called a dilation or enlargement. If a centre of enlargement is used, the distance of every point from the centre is multiplied by the scale factor. The scale factor can be negative in which case the distance to the new point is measured on the opposite side of the centre to the original point.
What is a transformation that slides a figure horizontally and vertically called?
A transformation that slides a figure horizontally is called a translation. A transformation that slides a figure vertically is also called a translation.
What is the transformation that reduces or enlarges a figure?
congruent figure
Is a transformation that proportionally reduces or enlarges a figure?
yes
Transformation that proportionally reduces or enlarges a figure?
Dilation is a linear transformation that enlarges or shrinks a figure proportionally. It is also referred to as uniform scaling in Euclidean geometry.
What do you call a transformation that enlarges or reduces a figure?
It is simply called an enlargement which is one of the four possible transformations on the Cartesian plane.
What is a transformation that proportionally reduces or enlarges a figure?
There are 4 transformations and they are:- 1 Enlargement which reduces or increases a shape proportionally 2 Rotation moves a shape around a fixed point 3 Reflection which produces a mirror image 4 Translation which moves a shape into a different position

What is The original figure in a transformation?
It is the figure before any transformation was applied to it.
